ccdproc + broken pipe

Hello,
I use IRAF as a part of Scisoft 7.5 on Ubuntu. Recently, I encountered the following problem, although IRAF worked smoothly on the computer for a long time (more than a year).
- --> epar ccdproc
Task ccdproc is running...
x_ccdred.e: 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.

Do you know what might cause this problem, or what I could check?
Thanks.

The error message indicates a memory corruption problem in CCDPROC, but that's about all. Since this is a v2.14.1 system you'd have to confirm the same problem is present in v2.15 and provide the data and params so we could try to reproduce it. If your IRAF system hasn't changed, it may be a data-specific problem you could isolate, e.g. invalid CCDSEC values or a corrupted file. Does the behavior change as you enable/disable individual parameters? Does it make a difference if you run the task under the CL instead of PyRAF? Does it work correctly on a different but similar machine (i.e. it is rare, but a bad memory chip could be the cause as well).
