This most likely is an application bug.
Hang in free usually means double free somehwere or overflowing a malloc
buffer.
Try ElectricFence on the application, or MALLOC_CHECK_=3, or valgrind.

The above link mentions #90301, which was fixed by
2003-04-19  Ulrich Drepper  <drepper redhat com>

        * stdlib/cxa_finalize.c (__cxa_finalize): Don't call
        UNREGISTER_ATFORK if d == NULL.

RHEL3 uses glibc CVS snapshot from 2003-09-26, so obviously this fix is in.
