 Whats the meaning of this stack trace

Hi:
One of my perl programs running as a daemon is dumping core when sent
an INT signal. I am only setting a global variable after catching the
signal.
Can someone please comment on what can be reason for this Core dump.
Here is the stack trace

bash-2.03$ perl -MDevel::CoreStack -e 'stack("/usr/bin/perl",
"./core")'
Executing /usr/bin/dbx "/usr/bin/perl" "./core" (where)...
dbx version 5.1
Type 'help' for help.
Core file created by program "job_daemon.pl"

thread 0x4 signal IOT/Abort trap at >*[__nxm_thread_kill,
0x3ff805cb1d8]        ret     zero, (ra), 1
