backtrace for DoDonPachi Resurrection

Steam game "DoDonPachi Resurrection" crashes with an XInput related error at
startup. All the other games by this developer (Cave) show the same behavior.

I've managed to figure the following out:

If using the portable-devel tarballs, the problem shows up as of version
wine-2.19

If I compile from source, I can reliably recreate the problem by including -O2
in my CFLAGS. It also appears to be an issue before 2.19, I'm not sure how far
back it goes but I saw the same behavior with the wine-2.10 git tag.
