Description Clemens Eisserer 2017-05-07 21:27:01 UTC

After updating Mesa-17.0.3 to 17.0.5 on my Haswell based fedora 25 laptop, Grid Autosport fails to start a race with:

Mesa 17.0.5 implementation error: Failed to compile tessellation evaluation shader: TES compile failed: no register to spill

and afterwards crashes inside libGl:

OpenGL dispatch[29034]: segfault at 68 ip 00007f5e60027beb sp 00007f5e2fffe140 error 4 in i965_dri.so[7f5e5fbfa000+721000]

Same issue here with the same game.

I'm using Fedora 29, Mesa 18.2.4. 

Mesa 18.2.4 implementation error: Failed to compile tessellation evaluation shader: TES compile
 failed: no register to spill

After the previous error, the game crashes (segfault).

Hi Jean-Charles,

I've reproduced segfault 
[28731.665163] OpenGL dispatch[26365]: segfault at 68 ip 00007f4177409b6b sp 00007f41097f9180 error 4 in i965_dri.so[7f417707c000+5e4000]

when race is starting on my Haswell. Currently investigating this issue.

Environment: Ubuntu 16.04; kernel 4.18.16; Haswell: CPU: Intel Core i5-4300M GPU: Intel® HD Graphics 4600.

Comment 3 Marina Chernish 2018-11-16 15:25:01 UTC

Works well on mesa 13.1.0, but crashes on 17.0.0, 18.0.5, 18.3.0 for my Haswell.
Bisected.
