Hello, I have been wondering why when debugging a given application I sometimes get an exception. It doesn't happen all the times but it does happen sometimes. It seems a non deterministic behavior: going thru an application with a number of breakpoints set I sometimes see an exception and other times everything goes fine (without having added or removed any of the breakpoints).

homunculus: depends on the application. if it has SEH, then maybe it has
a protection that uses exception to pass execution to the exception handler

No protections, I'm pretty sure. If it were a protection it would fire everytime ... while what I see is it firing once and not the following WITHOUT HAVING ADDED OR REMOVED ANY BREAKPOINT from one pass of code to the following.

Could still be protection - they don't occur every time, some only trigger every so often.
