If you're on Linux, you can turn SEGVs into Errors:

'cause it's not really that useful. uncaught (by the proper checks)
segmentation fault is the serious bug, program must crach and spit out
postmortem dump
In an environment that you don't control, the default behavior is likely
to print "Segmentation Fault" and exit. No core dump, no nothing.
This leads to unhelpful bug reports, and seeing if you can get your
client to "try to make it happen again with this debug build, or with
the shell set up to make a core dump".
I think it would be nice to be able to check if a core dump is enabled,
and if not, register the handler by default.
