allocation problems in FORTRAN [closed] up vote -4 down vote favorite I am having problems with the deallocate and allocate aspects of part of my FORTRAN code. in particular, i think that the issue has to do with memory allocation from a search on my error message on the web. The error message talks about invalid pointers, however, I am not using any pointers fortran allocate multiple arrays in my program After completing iteration # 2 of my f loop (see below), the program crashes or rather most of the time it crashes and sometimes it just freezes up. I am confident that this is the point where the bug is. as the program runs up to this point. I have subroutines not shown but since they work for other simulation combinations, I am reasonably confident that they are not the problem. I am using deallocate and allocate in other places within the program (successfully) so I am surprised that it is not working here. I am only showing part of the program for ease of reading. in particular, I have removed my calls to the subroutines that I wrote. I hope that i have provided sufficient info for you programmers to help me figure out the problem. if not please specify what other info you want and I will be happy to comply. I have compiled the program using various compiler options and have fixed some bugs and removed any warnings. At this point, however, the compiler options do not give me any more info. allocate(poffvect(1:6)) allocate(phi1out(1:1)) allocate(phi2out(1:1)) allocate(phi1outs1

list of pointers or allocatable arrays. http://www.lahey.com/docs/lfprohelp/F95ARDEALLOCATEStmt.htm stat-variable is a scalar INTEGER variable that http://www.ibm.com/support/knowledgecenter/SS2MB5_14.1.0/com.ibm.xlf141.bg.doc/language_ref/dealloc.html returns a status value. Remarks If the optional STAT= is present and the DEALLOCATE statement succeeds, stat-variable is assigned the value zero. If STAT= is present and fortran allocate the DEALLOCATE statement fails, stat-variable is assigned the number of the error message generated at runtime. If an error condition occurs during execution of a DEALLOCATE statement that does not contain the STAT= specifier, the fortran allocate array executable program is terminated. Deallocating an allocatable array that is not currently allocated or a pointer that is disassociated or whose target was not allocated causes an error condition in the DEALLOCATE statement. If a pointer is currently associated with an allocatable array, the pointer must not be deallocated. Deallocating an allocatable array or pointer causes the status of any pointer associated with it to become undefined. Example integer,pointer,dimension(:,:) :: ip => null() integer,allocatable,dimension(:) :: jp integer :: allostat allocate (ip(10,20),jp(10)) deallocate(ip) deallocate(jp,stat=allostat) write(*,*) allostat See Also Allocate Statement Send comments on this topic. ©2004 Lahey Computer Systems, Inc.

There are many reasons why Deallocate Error happen, including having malware, spyware, or programs not installing properly. You can have all kinds of system conflicts, registry errors, and Active X errors. Reimage specializes in Windows repair. It scans and diagnoses, then repairs, your damaged PC with technology that not only fixes your Windows Operating System, but also reverses the damage already done with a full database of replacement files.
A FREE Scan (approx. 5 minutes) into your PC's Windows Operating System detects problems divided into 3 categories - Hardware, Security and Stability. At the end of the scan, you can review your PC's Hardware, Security and Stability in comparison with a worldwide average. You can review a summary of the problems detected during your scan. Will Reimage fix my Deallocate Error problem? There's no way to tell without running the program. The state of people's computers varies wildly, depending on the different specs and software they're running, so even if reimage could fix Deallocate Error on one machine doesn't necessarily mean it will fix it on all machines. Thankfully it only takes minutes to run a scan and see what issues Reimage can detect and fix.
A Windows error is an error that happens when an unexpected condition occurs or when a desired operation has failed. When you have an error in Windows, it may be critical and cause your programs to freeze and crash or it may be seemingly harmless yet annoying.
A stop error screen or bug check screen, commonly called a blue screen of death (also known as a BSoD, bluescreen), is caused by a fatal system error and is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to "crash".
One of the biggest causes of DLL's becoming corrupt/damaged is the practice of constantly installing and uninstalling programs. This often means that DLL's will get overwritten by newer versions when a new program is installed, for example. This causes problems for those applications and programs that still need the old version to operate. Thus, the program begins to malfunction and crash.
Computer hanging or freezing occurs when either a program or the whole system ceases to respond to inputs. In the most commonly encountered scenario, a program freezes and all windows belonging to the frozen program become static. Almost always, the only way to recover from a system freeze is to reboot the machine, usually by power cycling with an on/off or reset button.
Once your computer has been infected with a virus, it's no longer the same. After removing it with your anti-virus software, you're often left with lingering side-effects. Technically, your computer might no longer be infected, but that doesn't mean it's error-free. Even simply removing a virus can actually harm your system.
Reimage repairs and replaces all critical Windows system files needed to run and restart correctly, without harming your user data. Reimage also restores compromised system settings and registry values to their default Microsoft settings. You may always return your system to its pre-repair condition.
