Possible problem with gdb on GNU/Linux RedHat 7 Intel

[Charlie Zender]

Hi,

I'm running RedHat 7 on an i686, gdb 5.0. 
Attached is a report of possible problem with gdb.
The example shows that a C++ program loads and runs fine during the
first call to gdb, but that it fails on all subsequent runs.
The error message is 

"/home/zender/bin/LINUX/ccc: error while loading shared libraries:
libpthread.so.0: failed to map segment from shared object: Cannot
allocate memory"

This message is over my head, perhaps it's not gdb-related at all.
But it seems strange the program behavior changes within gdb.
The program runs fine, repeatedly, from the shell command line.
Again, my installation is stock RedHat 7, with all updates applied.
I'm not smart enough to fiddle with threads so I have no idea why 
there is an error coming from libpthread.

Any help appreciated. Willing to provide more info if needed.

Thanks,
Charlie
