Bug ID: 54154 Summary: winmm:midi sometimes crashes on exit in Wine Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: NEW Severity: normal Priority: P2 Component: winmm&mci Assignee: wine-bugs@winehq.org Reporter: fgouget@codeweavers.com Distribution: ---
winmm:midi sometimes crashes on exit in Wine:
0494:midi: 445 tests executed (4 marked as todo, 0 as flaky, 0 failures), 0 skipped. winmm:midi:0494 done (-1073741819) in 7s 5788B
See https://test.winehq.org/data/patterns.html#winmm:midi
Where -1073741819 == 0xc0000005
The pid of the test summary line matches the one printed by the WineTest executable which means this is the summary line of the main process. That means the crash happens on exit, probably as the result of memory / stack corruption.
There have been 24 crashes in the past 6 months but they became more frequent after the 2022-09-16 which may correspond to the TestBot switching to running two VMs are a time. So the failure may be caused by extra load.
There is also at least one case of a timeout on exit (2022-12-09 on debian11-win32-ja-JP), which is probably the same issue:
05fc:midi: 445 tests executed (4 marked as todo, 0 as flaky, 0 failures), 0 skipped. winmm:midi:05fc done (258) in 120s 5788B
