Package: wine Version: 10.0~repack-6 Severity: normal Tags: patch X-Debbugs-Cc: [email protected], [email protected] User: [email protected] Usertags: arm64
Dear Maintainer, When running Wine on arm64, on HW with pointer authentication (armv8.3 and newer), Wine fails to run. In some cases, it hangs directly on startup for any case (e.g. "wine wineboot" hangs), in some cases it seemingly runs successfully, but any case that requires unwinding in the user executables fail. (Exactly what makes it seemingly succeed in some cases and hang in others is unclear.) The issue can be consistently observed by running "WINEDEBUG=+seh wine wineboot" in a fresh install with no preexisting wine prefix (~/.wine). On older hardware, without support for pointer authentication, Wine starts up nicely (and there are a handful of debug printouts about unwinding one exception). On newer hardware, it results in repeated printouts about EXCEPTION_ILLEGAL_INSTRUCTION. The root cause of this issue is that Clang 19 and newer has regressed the code generation for return address signing on Windows on aarch64 - this issue has been filed upstream at [1]. Debian builds of Wine have pointer authentication enabled for the internal PE components of Wine (and those components are compiled with Clang), which causes Wine to trip over itself when unwinding through those components. However, the issue is made visible due to the fact that Wine's unwinding of pointer authentication was more strict than what really is necessary. A fix for this was merged in [2]. This fix avoids triggering illegal instructions and breaking on these cases. This fix will be in the upcoming development release Wine 11.12, but it also applies cleanly on e.g. Wine 10.0. Applying this patch in the Debian packaging will likely fix this issue.
