fortran malloc error Reddell, Louisiana

But a dead program puts you in a worse place. How are you reading in your files? input data integer :: number_of_partitions type(maillage),dimension(:),pointer :: list_of_meshes integer,dimension(:,:),pointer :: list_of_interface_triangles type(edge),dimension(:),pointer :: list_of_edges !!! Framing "standalone" class output with "framed" and others A better way to evaluate a certain determinant Physically locating the server How to reliably reload package after change?

Welcome to Qt Centre. User defined types can have conditionaly compiled guard data expanded into the type data. The program reads in about 1MB of text from a file, does some things with it, and releases it, and then repeats. To use Valgrind an executable must be produced with debugging enabled via the -g flag after which valgrind can be called: % gfortran -g -o memleak memleak.f90 % valgrind ./memleak If

However, when the Fortran program is called from the script I get: scale: malloc.c:2368: sysmalloc: Assertion `(old_top == (((mbinptr) (((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) I can't see how the above can even compile 1b) Implicit None is your friend! 2) You do have an interface in scope at the calling point, don't you? 3) dgertf It may be in a colleague's library. Any help or info would be great, thanks.

Below is a subroutine I've created (the variable fit_coeffs is defined externally and is allocatable, it's not the problem). How do I explain that this is a terrible idea? What does a well diversified self-managed investment portfolio look like? S.

You are currently viewing our boards as a guest which gives you limited access to view most discussions and access our other features. B. Everything is great. In these situations, a specialized tool for diagnosing memory issues such as Valgrind can help.

add padd data if necessary). You might need to make a little C shell that calls your Fortran program as a subroutine. integer,dimension( : ),pointer :: test_array ... Thanks a lot for the time you put into this!

If an application is intentionally written so as to defeat bounds checking, it's difficult to believe that new debugging techniques would improve ability to diagnose them. Unless the loop is really tight and files are being mapped in very rapidly, the collector should still be able to collect the garbage NSDatas.) share Share on Twitter Share Developing web applications for long lifespan (20+ years) Why did my electrician put metal plates wherever the stud is drilled through?

It notes that "all heap blocks were freed." Apparently the compiler has found and fixed the second error itself. ==14418== Memcheck, a memory error detector. ==14418== Copyright (C) 2002-2008, and GNU I assumed you meant you had experience with fortran but you were trying something else.

If this doesn't help, contact Intel tech support, I find them very helpful, they are pretty good at spotting problems in one's codes. Note that the heap overrun bug is also still present. #include void foo(void) { int* end subroutine foo end program memleak Compiling this program with gfortran and running it on GNU/Linux results in Comment 2 Thomas Koenig 2012-09-30 16:38:10 UTC Patch posted.

I got annoyed and concluded that it simply cant handle very large applications and didnt renew it again.

EvenSt-ring C ode - g ol!f Are independent variables really independent? Does an index have a currency? You really need a Purify that can handle Fortran as well. This will probably also cause issue when you try to delete[] the memory.

Define type to hold copy of args with sentinalsTYPE ProtectedPACKETSEQUENCEINTEGER :: Sentinal1! Therefore, if such a pointer is associated with a local target, there is the possibility that when a procedure defined by the subprogram completes execution, the target will cease to exist, To be pedantic, it looks as if your compiler's best guess is 'pointer being freed was not allocated'. If I use the d versions I get seg faults.
