--- Comment #8 from Peter Wu <lekensteyn at gmail.com> ---
bisecting with the small program (via glretrace) and ASN + -O0 and -g still
points to the same faulty commit:

a3ae5dc7dd5c2f8893f86a920247e690e550ebd4 is the first bad commit
commit a3ae5dc7dd5c2f8893f86a920247e690e550ebd4

    draw: make sure that the stages setup outputs

    Calling the prepare outputs cleans up the slot assignments
    for outputs, unfortunately aapoint and aaline didn't have
    code to reset their slots after the initial setup, this
    was messing up our slot assignments. The unfilled stage
    was just missing the initial assignment of the face slot.
    This fixes all of the reported piglit failures.
