7ffc1fb928268f8493e88d45e9a006208d05f0f6 is the first bad commit commit 7ffc1fb928268f8493e88d45e9a006208d05f0f6 Author: Marek Olšák <marek.olsak@amd.com> Date: Thu Mar 19 23:27:10 2015 +0100 gallium: bump shader input and output limits Reviewed-by: Roland Scheidegger <sroland@vmware.com> Signed-off-by: Marek Olšák <marek.olsak@amd.com> :040000 040000 c8ba9549231eff63c36137320a597d586a53298a a53d5640b434fc002eca189ffcb19aec79e1755a M src bisect run success This is the same as bug 90539. And the change in http://cgit.freedesktop.org/~jrfonseca/mesa/commit/?h=max-varyings fixes the assertion. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
