ccminer actually crashed:
Unhandled exception at 0x00C99824 in ccminer.exe: Stack cookie instrumentation code detected a stack-based buffer overrun.
same crash if you run ccminer with a paramater that is not recognized.. like
ccminer --not-implemented
crash. Doesn't exit properly on windows.
Without --no-gbt it crashes too:

I think it happens when ccminer is trying to send a result.
