Summary: Memory corruption (crash) in
draw/draw_pt_fetch_shade_pipeline_llvm.c:435
Severity: normal
Classification: Unclassified

gdb bt full
After upgrading Mesa 9.2.4 to 10.0.1, my Java program using JOGL crashes with a
memory corruption error.
The attached GDB log was generated with Mesa
a3ae5dc7dd5c2f8893f86a920247e690e550ebd4 ("draw: make sure that the stages
setup outputs"), built with --enable-debug.
I enforce software rendering because that gives me in an order of magnitude
better fps than i965 (glReadPixel is slow.):
LIBGL_ALWAYS_SOFTWARE=1 java -cp ... RobotRace
With some versions of my program (new member variable, no other side-effects),
it immediately crashes. For other versions, it crashes after modifying the
center point in gl.glLookAt(). Let me know if you need more details (source,
etc.).
Bisection leads to:
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.
