If a non-Wine thread gets USR1 or USR2 it didn't come from us, and handing it to a Wine thread is not going to do the right thing. Note that signal masks are per-thread, but according to my understanding signal *actions* aren't. QUIT is supposed to kill the entire process by default, not just a thread, so just killing that thread doesn't seem right. I suppose we *could* exit() in that case, but QUIT also dumps core by default, so it doesn't seem quite right to do a clean exit either. At least not right enough to be worth the extra complexity. Rethrowing INT to a Wine thread is... nontrivial, but possible, I guess? I'd rather leave it for a follow-up patch if it's really worth doing. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2126#note_23484

Well we currently crash indeed but I don't think it is intentional. Making it explicit would make it look more like it is. I'd think that instead we should block the signals in the threads that cannot handle them, or handle them in a way that doesn't require a TEB. USR1 / USR2 / INT for instance could be blocked in non-Wine threads, raising them again until they reach a Wine thread. I think QUIT should be handled properly by calling `pthread_cancel` or `pthread_exit` and letting the thread cleanup properly. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2126#note_23475

Without this patch the process will silently die. I managed to trigger this while trying to trace Child of Light with Renderdoc, the latter of which crashed in its own "TargetControlServerThread". This, confusingly, manifested in the game restarting itself without the Ubisoft overlay; apparently the game or one of its launchers was capable of recognizing when the process had died and restarting it, but would not try to inject the overlay a second time. I have not investigated the cause of the crash; it is not unlikely that it resulted from the overlay injection (despite the fact that that should only directly affect PE code.) -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2126

[PATCH v5 0/1] MR2132: vbscript: Fix memory leak in interp_redim_preserve
by Jason Millard (＠jsm174) 08 Feb '23

08 Feb '23

While running in XCode's profiler, I noticed two memory leaks in `interp_redim_preserve`. After looking at `interp_redim`, the `bounds` structure is freed. I've updated `interp_redim_preserve` to free `bounds` when the array is NULL and not NULL. -- v5: vbscript: Fix memory leak in Split() https://gitlab.winehq.org/wine/wine/-/merge_requests/2132
