Debugging standard universe problems is pretty tough because the
checkpointing and remote i/o libraries live in the same vm space as the
user code itself. So, what we should do at this point is to have you check
your program with various memory checkers like valgrind(3.2.1 or later)
and whatnot to give it a clean bill of health. The standard universe
codebase really alters the memory usage patterns of applications and
has a tendancy to flush out previously hidden bugs.

In addition to the above, can you answer these few questions:

Is it threaded? If so by what method? (cooperative threading or NPTL with
pthreads?)

Are you using the STL?

When your application is compiled with -g, what is the full backtrace
of the error? Try it both with gcc 4.1.0 and gcc 3.4.6.

Thank you.
