Hello,

But it definitely has an influence on how many
functions pass the safedisc check. Was just a thought that this might explain
the differences we are seeing.

Yep, the gcc 4.1.2 snippet was just an example to show every gcc version
behaves different (might generate different entry code).

When compiled with -fstack-protector this function will pass the safedisc
check, without it would fail.
--- quote ---

Yes, it is the stack protectors 3 additional instructions that makes more
functions pass because they move the PIC load (first call) beyond SafeDisc 2.x
analyzer threshold of 8 entry code instructions.

Considering the wide range of used gcc versions more user32 functions should be
marked hidden to gain more distance to analyzer c2 threshold.

Regards
