medm with epics-base 3.14.6+

[Emmanuel Mayssat <emmanuel_mayssat@lynceantech.com>]

Hello,

I am trying to update my driver to a more recent epics base.
I assume that if I do so, I need to recompile the epics extensions.

The issue I face is with medm 3_1_1 and 3_1_2_1 (the latest version) on
the base R 3.14.9 (and R 3.14.8.2 ).
Medm builds correctly, but when I start and ioc and attach a medm
display to it it immediately freeze. 
The behavior I observe is as if the process was sleeping (I can move the
window, but display do not refresh and is blanked when I bring other
gnome widgets on the top of the medm window).

NOte: medm 3_1_1 works correctly on epics base 3.14.6 on same machine

It seems to be an issue with the channel access.
As anybody seen this before?
I am running on linux RH8.0 (default install)

Regards,
