fopen/fclose give segfaults

[Daniel Senderowicz <daniel bicho SynchroDS COM>]

Hi,

I'm new to linux and this list, so please bear with me if this
problem was already posted before.

I compiled a program that opens a few files with fopen and fclose.
When I run it it gives some segmentation faults.  According to gdb,
the problem appears when fopen/fclose in turn call some malloc/free
functions. This is confirmed when I set MALLOC_CHECK_=1, that
mentions something abount a bad pointer to free(). This program
runs perfectly on a NetBSD machine (mips), so I'm wondering if that
is a particular problem of linux, or the gnu library and if there
is a solution for that. Thanks in advance.

Dan
