I've got half a dozen reports of a espeak crash on Fedora 21/22. Full
backtrace with debug symbols etc at the following links if that helps.

https://bugzilla.redhat.com/show_bug.cgi?id=1225853
https://retrace.fedoraproject.org/faf/reports/667971/

There's also a minor patch for a festival crash I keep meaning to send
upstream for review here:
