Description Pierre Ossman cendio 2010-10-12 14:22:30 CEST
One of the tests run by piglit causes our server to crash. This bug was present in 3.1.1 as well as the upgraded Mesa in 3.1.2. Haven't investigated exactly what test causes the crash.

Can be reproduced by running all tests in piglit. Crashes once it starts with the glean tests.
Comment 1 Pierre Ossman cendio 2016-05-11 16:32:45 CEST
This bug is still present. xinit.log has this:

> Xvnc: ../../../src/mesa/swrast/s_texture.c:163: _mesa_check_map_teximage: Assertion `x < texImage->Width || texImage->Width == 0' failed.

The last succeeding command is:

> /home/cendio/piglit/bin/arb_texture_compression-invalid-formats s3tc -auto -fbo

And the one after that (that fails because the X server vanishes) is:

> /home/cendio/piglit/bin/s3tc-errors -auto -fbo

The name seems to be "spec@ext_texture_compression_s3tc@s3tc-errors".
Comment 2 Pierre Ossman cendio 2018-09-11 16:45:13 CEST
Tested again with our upgraded Xorg and Mesa on Fedora 28. I still get a crash, but this time a SIGSEGV:
