When using gcc compiler (as opposed to llvm) to build 32 bit tcc, compiler flags -mpreferred-stack-boundary=2, -march=i386 and -falign-functions=2 were being used. -march is redundant as -m32 is already being used. The other two seem to be corrupting stack. I am not sure why this is the case, as the explanation of the flags states that only running code size should be affected, but it does. I think that is is safe to remove these flags altogether for all compilers and platforms, especially since they are not being used for 64 bit builds. However I do not want to apply such wide change without agreement from the people on the mailing list.
