That's weird.  If that ktrace is right, that means the program is seg
faulting, the SIGSEGV handler is set to its default (i.e. kill the
process), but the process is not being killed.  That should not happen :) .

Try attaching to the process with gdb ("gdb 1234", or whatever the pid
of the process is) and print a live stack trace from that.
