[Cc'ed to -ports again, just FYI]
Ah! I know why it doesn't work!
Somebody attempts to catch SIGKILL. This is an error in the first
place, and the signal handling facilities do report it:
SIGACTION(2) UNIX Programmer's Manual SIGACTION(2)
NAME
sigaction - software signal facilities
ERRORS
Sigaction() will fail and no new signal handler will be installed if one
of the following occurs:
...
[EINVAL] An attempt is made to ignore or supply a handler for
SIGKILL or SIGSTOP.
So perhaps other shells are broken enough to ignore this error, while
our one isn't.
Btw., it's interesting that the trap on SIGBUS, but not on SIGSEGV.
Doesn't sound to be too rational, either.

Never trust an operating system you don't have sources for. ;-)
