The Wine-Staging patch that causes the crash.
A recent update to Roblox Player cause Wine-staging to crash with the error "An
unexpected error occurred and Roblox needs to quit. We're sorry!".
To locate the exact patchset that caused the issue, I created a bisect tool in
Python that allows me to approximately rule out half of the patchsets every
rebuild.
After few rounds of bisection, I discovered that by skipping just the
server-default_integrity patchset, Roblox Player no longer crash.
I did further bisect and found that applying
"0007-ntdll-Elevate-processes-if-requested-in-RtlCreateUse.patch" causes Roblox
Player to crash.
The patch was introduced on commit be3928a8091e36197bc9894c4a09f13cf5459138
(server-default_integrity: Elevate processes if the manifest requests.), which
is supposed to fix Bug ID 51000.
The patch file itself is attached below to make the discussion easier.
