--- Comment #27 from Michael Stefaniuc mstefani@winehq.org --- Of course there are extensive tests in a separate commit. https://source.winehq.org/git/wine.git/commitdiff/296a1eb77bc9e10deb9a8a8cbe...
The patch submission had some additional information on what I've tested. https://source.winehq.org/patches/data/176042 "Fixes memory corruption related crashes: - Fixes bug 17766, tested with Empire Earth Demo. - Should fix bug 24740 too as that is the origin of the workaround included in Staging. But BigFish GameLauncher is a pita so can't test. - Fixes the first crash in bug 31562 and lets the game continue until it hits the next crash (unrelated to PChannels)."
Also there is a third follow up patch to remove some of the todo_wine() from the tests. But that's risky so it will have to wait for the code freeze to end: https://source.winehq.org/patches/data/176044
