--- Comment #6 from José Fonseca <jfonseca at vmware.com> ---
I've been fiddling with this, and I only see two things that workaround this
MSVC bug:
- disable all optmizations (/O0 isntead of /O2 or /O1)
- force all bit fields from struct prog_src_register to have the same signness
(either all unsigned, or all signed), ie, the problem here seems to be the
intermixing

Still, this is a scary bug. We use this all over the place.

BTW, it also fails with MSVS 11 Beta.
