Jonas, where am I supposed to add this options?
I tried adding
--eval-command="handle SIGUSR1 nostop noprint pass"
to
Debugger_Startup_Options
but that didn't help. Actually nothing happened until I restarted the IDE.
After the restart the first run showed
---
Initialization output:
&"Undefined command:\"\".Try \"help\".\n"
--
To ensure the string is correct I tried
gdb --eval-command="handle SIGUSR1 nostop noprint pass"
from terminal and it worked.
Is it possible that some procedure makes c-style string translation (" ->
\") while actually it isn't necessary here?

Hmm, it seems that it's not a 'wrong' exception, I executed the same program from console and it worked. So there's a range of signals that is 'wrong' for the debugger/ide and it stops catching them. It's not considered as "wrong" by gdb. By default it simply catches all signals. If you type "cont" at that point, the program will continue execution and the signal will be delivered to the program.
