Allocation Error

[janos]

Hello,

I've created a program with Intel Fortran Compiler 11.1 using openSUSE 11.2 and get such a mistake:

malloc.c:3096: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) >= (unsigned long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) - 1))) && ((old_top)->size & 0x1) && ((unsigned long)old_end & pagemask) == 0)' failed.
Abgebrochen

I'm using this command line to compile the program:

ifort *.f90 -g -traceback -o bem_kontakt

Normally I get the line inside the program where I could find the mistake.

I've tested the program. The main program is callig a subroutine twice. The first call works well, but the error occurs during the second call of the program.

How can I find such a mistake.

Thanks in advance

Hi janos,

You can try running in a debugger with breakpoints set for symbols like 'abort' and 'exit'. You may have to

experiment to get the right symbol. When you program hits the breakpoint, you should be able to get a

stack trace to see where the call to malloc came from in your program.

Another comment: OpenSUSE 11.2 is too new to be supported. We do not test on this OS, so it is possible that the traceback, which relies on the system's gcc and libc, may not work correctly. Is it possible to try this program on an older OpenSUSE?
