I did read that but I hoped it was someone having unrelated problems. I
guess it's not.
So, neither CreateThread nor MSVCRT align the stack, so I guess you'll
have to do it yourself. You should be able to do this with something
like:
asm __volatile__ ("andl $-16, %%esp" : : : "%esp");
at the beginning of your thread function. You could probably do this in
a wrapper-function that calls your actual thread function too.
You might also want to ask this on the MinGW list, as they'd know if
there was a better solution.
