I was trying to test new mesa with my usual array of wine benchmarks and games and noticed wine started to abort after I updated mesa from ~ 4 nov 2020 to ~12.12.2020.

Currently running git bisect, results so far:

sight, git bisect noticed my reverts needed for clover linking on my system :/

but at least I have some pointers (compilation a bit slow on this machine, ~ hour for full mesa build, don't want to alter build flags for minimizing uncertanity).

wine error looks like this:
