Bug ID: 54347
           Summary: winealsa's MIDI support sometimes causes a
                    dmloader:loader stack overflow in Wine
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: winealsa.drv
          Assignee: [e-mail]
          Reporter: [e-mail]

winealsa's MIDI support sometimes causes a dmloader:loader stack overflow in
Wine:

01e0:Call KERNEL32.SetThreadDescription(fffffffe,01e1c034
L"winealsa_midi_notify") ret=01e1128e
...
01e0:err:virtual:virtual_setup_exception stack overflow 900 bytes addr
0x7bc56a8d stack 0x1e90c7c (0x1e90000-0x1e91000-0x2090000)

On test.winehq.org this probably corresponds to the c0000005 crashes though to
be sure one would need to have access to the Wine traces and +relay or
something to identify the overflowing thread:

0530:loader: 104 tests executed (0 marked as todo, 0 as flaky, 0 failures), 0
skipped.
dmloader:loader:0530 done (-1073741819) in 0s 88B
Test failed: crash (c0000005)

See https://test.winehq.org/data/patterns.html#dmloader:loader

Looking at the corresponding TestBot jobs one can see two instances per run but
there are not enough traces to match the thread to winealsa's midi thread:

05a4:err:virtual:virtual_setup_exception stack overflow 900 bytes addr
0x7bc56a8d stack 0x4dc0c7c (0x4dc0000-0x4dc1000-0x4fc0000)
05a4:err:virtual:virtual_setup_exception nested exception on signal stack addr
(nil) stack 0x7ff6ecac
...
0210:err:virtual:virtual_setup_exception stack overflow 900 bytes addr
0x7bc56a8d stack 0x2fd0c7c (0x2fd0000-0x2fd1000-0x31d0000)
0210:err:virtual:virtual_setup_exception nested exception on signal stack addr
(nil) stack 0x7ff9ecac

It's also hard to match those to specific tests because the 'Running' lines are
out of sync but the second instance looks like it could be from dmloader:loader
while the former would be from an earlier test, possibly amstream:amstream.

--- Comment #1 from François Gouget  ---
This issue can also happen in amstream:amstream and winmm:mci which makes sense
since they also cause winealsa.drv to be loaded.
winmm:midi obviously also causes winealsa's midi support to be initialized but
it seems to only get the critical section issue (see bug 54346).

I have confirmed this to also impact quartz:filtermapper and qcap:capturegraph.
