A quick try of this patch alone -> still get the same crash? --------------------------------------------------- Thread 1 "X" received signal SIGSEGV, Segmentation fault. 0x00007f4666cd5c2a in isl_format_supports_ccs_e (devinfo=devinfo@entry=0x1aa72e8, format=ISL_FORMAT_UNSUPPORTED) at isl/isl_format.c:558 558 isl/isl_format.c: No such file or directory.

With Weston/Xwayland this is even easier to trigger. It's enough to run any X program (like xrandr or xhost), something that doesn't even use Mesa itself, and both Xwayland and Weston come crashing down. I was unable to get backtrace out of Xwayland (with gdb server, Gdb wasn't able to get sync for some reason), but the same one-liner fix in <a href="show_bug.cgi?id=106642#c1">comment 1</a> gets rid of that crash too.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
