Running Windows 10 / and 64, version 1809, build 17758.4 and claws-mail -

CM crashes sporadically when opening emails. I tried to debug it; however, CM
always crashes when run under the debugger.

Since CM crashed prior to attempting to open an email, I cannot get any further
info. By the way, how do I run CM with "--debug" under the GDB debugger?
