Re: Dealed with gcc bug 36834 - structure return ABI for windows targets differs from native MSVC ?

Yes, beginning with 4.7 version of gcc the proper caller pops

My question is, can libffi automagically detect the two different behavior and correctly call a dll compiled with older gcc compilers?

It seems the gcc bug commit include some unit test that can somehow detect the different return behaviors. But I really don't know a thing about compiler or ABI. :(
