Uncompressing exe is not problem or I can analysed produced ASM code. Trying with debuger or simply run test is problematic because you have no chance to test all code. If it is more complex program than some simple command line utility working on file/stream there are too much branching to test all cases if somewhere it crash on invalid opcode...

I search and it seems that's not supported here. Only by some external tools, as you said, I also read about valgrind but didn't tried...
