--- Comment #9 from Tvrtko Ursulin <tvrtko.ursulin at linux.intel.com> --- Thanks Emil! Unfortunaltey I am not familiar with Optimus nor do I have appropriate hardware. Could someone provide a backtrace (with symbols) of the binary which ends up saying "malloc: unknown:0: assertion botched", etc? Or maybe even Valgrind it? Although that may be pretty advanced. I don't think this commit is the actual culprit, but it is possible that the failing binary uses UserPtr if it detects it, and has a bug in those optional code paths. Another interesting test would be to try non-working libdrm on a kernel without UserPtr support. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
