This is actually expected behavior.
'factorial' is the test program for the debug engine (dbug) that mysql uses.
It has 5 testcases that are always used during building, and some of them should never complete. The idea is the test program must crash, and then you can compare it's backtrace against an expected backtrace to see if things are sane.

The rlimit_core message is not the usual one that the exit with however - they usually just segfault as designed.
