It is possible to configure which events should be ignored by the debugger. Aka exceptions.
The 'ie' command refers to 'ignore events'
[0x4A13B8C0]> !ie
0 stop
0 trap
0 pipe
0 alarm
0 fpe
0 ill
[0x4A13B8C0]> !ie stop
[0x4A13B8C0]> !ie | grep stop
1 stop
This is usually used to bypass some packer protections that relay on some events. So this way you can skip them just with '!ie stop' or '!ie -stop'.
