Hi, Pierrick.
You could run it in a debugger and try to see what's wrong.
Are you running Linux or Mac OS X (or some other UNIX-like OS)? If so,
you could use GDB. Say your edm screen is named motor.edl; you could do
the following:
$ gdb edm
(gdb) run -x motor.edl
Once it crashes, you can issue the bt command to get a backtrace:
(gdb) bt
Or, if edm is multithreaded, you could get a backtrace for all threads:
(gdb) thread apply all bt
If you don't understand the gdb, you could post it here and hopefully
someone would be able to help. You should also state the version of
EPICS and edm you're using and the operating system and version you're
using.
