By debugging kgm1 crackme from: http://www.crackmes.de/users/ascii/kgm1/ site, I encountered on such a problem. When I'm trying to debug crackme with gdb (anything else I'm not trying - I'm on linux), debugger shows segmentation fault.
So I'm asking what I'm doing wrong.
I'm setting breakpoint on entrypoint and it shows error on push eax
