[Freeswitch-users] easy way to crash freeswitch

[Steven Ayre]

Anything that crashes FS is *always* a bug, and should be fixed.

Please test it on git head of the master branch to confirm if it still
applies there, or whether it is a bug that has already been resolved.

Bugs can be reporterd at http://jira.freeswitch.org/

There is never a 'good' bug for sysadmins... 'fsctl crash' will
intentionally crash FS with much less effort if you ever need to test crash
handling.
