You may be able to declare your handler in gcc also as fastcall to work around this, but I don't know by heart how this is done. Or you may simply not pass any parameters at all. Ok, nice! As I know exactly where and when the exception might be thrown, I don't need to pass any params. As an aside, is there a way to register signal handlers scope-wise? That is, only to intercept a signal within a specific scope? Even though the library call is the only place where this happens, I guess that signal handling is global for the entire process?
