I looked up your bug; The comment from engineering was:

[BEGIN]
There is no signal handling for CFM or mach-o apps. While signal handling
may be done by traditional BSD libraries, we don't handle signals on behalf
of applications in CFM or CarbonCore for that matter.

This behaves as designed. The application workaround is to install a signal
handler for the desired signals based on signal(3).
