Sounds familiar. I'll try that. I have had that issue with other

programs. I think Ubuntu sets it pretty small by default.

That sounds very much like a regular stack overflow… I’m not sure how you change stack size -
is it ulimit -s ?

I've attached a medm screen. I'm having problems with the Bar Monitor

In edit mode:

Setting direction to "up" gives:
*** stack smashing detected ***: medm terminated

Setting display precision to User Specified gives:
SIGSEGV

[1]+  Aborted                 (core dumped) medm scintscal.adl

This is with medm-3.1.9 and epics base-3.14.12.4 on Ubuntu 14.10.

I built medm-3.1.9 on Ubuntu 14.04-LTS and just managed to get a SIGSEGV
from it when playing around with User Specified, but couldn't replicate
it yet when running under gdb.
