* SIGILL has not been tested.
|

* SIGFPE doesn't seem to work?

* SIGSEGV does not catch writing to a NULL pointer (that shuts down
|

* your app; can you say "segmentation violation core dump"?).

* SIGTERM comes from what kind of termination request exactly?

* SIGBREAK is indeed produced by pressing Ctrl-Break.
|

* SIGABRT is produced by calling abort.
|

* TODO: The above results may be related to not installing an appropriate
|

* structured exception handling frame. Results may be better if I ever
