             Bug #: 52957
           Summary: [r200] piglit glean/vp1-LIT test 2 (degenerate case: 0
                    ^ 0 -> 1) test fails
    Classification: Unclassified
           Product: Mesa
           Version: 8.0
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r200
        AssignedTo: dri-devel at lists.freedesktop.org

System configuration :

- radeon 9000 AGP ( M9, rv250 )
- laptop pentium 4 2.4 Ghz 1.25 Gb ram
- archlinux 32 bits

Step to reproduce the bug

- mesa 8.0.4 release ( but the bug occurs also with the git version )
- a graphic card who uses the r200 driver 
- install piglit ( git version )
- run the glean test "vp1-LIT test 2 (degenerate case: 0 ^ 0 -> 1)" in piglit :

./piglit-run.py  -t "glean/vp1-LIT test 2 (degenerate case" tests/quick.tests
results/quick

the glean/vp1-LIT test 2 (degenerate case: 0 ^ 0 -> 1) will fail with this
error message :

Vertex Program test 1: test a specific set of vertex programs.

FAILURE:
