As I tend to agree with Tom re this being a kernel issue, try (as root):
# Enable stack dumps etc via sysrq
echo 8 > /proc/sys/kernel/sysrq
# Trigger kernel stack dump of all processes via sysrq mechanism
echo t > /proc/sysrq-trigger
... then search the kernel log files to find the kernel stack dump
associated with your test program.
If you're not on the latest kernel for your OS, you should update it.
