Hi Andrew,
That PR builds OK on Centos 7, but it fails to build on Ubuntu 18. I see the same failure on Ubuntu 18 with the MEDM_3_1_14 tag.

Any idea what is wrong here?

There is a Pull Request against MEDM on GitHub<https://github.com/epics-extensions/medm/pull/4> which solved some issues on Ubuntu that might be causing this, Mark or Pete can you see if that helps?

Subject: MEDM crash
If, in MEDM edit mode, I try to change the numeric format for a field (say, from decimal to engineering), MEDM crashes with:
*** stack smashing detected ***: terminated
Aborted
This is on Ubuntu 20.04, MEDM Version 3.1.15, EPICS 3.15.6
Any ideas?
Pete.
