             Bug #: 29035
           Summary: winmm deadlock at exit
           Product: Wine
           Version: 1.3.32
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Keywords: regression
          Severity: normal
          Priority: P2
         Component: winmm&mci
        AssignedTo: wine-bugs at winehq.org

Winmm now deadlocks at exit when it failed to play a sound concurrently.

Use my MCI shell from bug #20232, comment #10:
wine wintest.exe mcishell
open z:\usr\share\sounds\ekiga\newmessage.wav alias nm
open z:\usr\share\sounds\ekiga\ring.wav alias ri
set nm output 1
set ri output 1
play ri from 0 notify
This will use "plughw:0" instead of "default" on ALSA. Now copy&paste these 2
lines at once:
play nm from 0
play ri from 0 wait

The first sound will play while the second one gets:
err:winmm:WINMM_OpenDevice Activate failed: 80004005
mci.c:1326: Test failed: mci play ri from 0 wait error: 265(9
MCIERR_DEVICE_OPEN)

Everything seems normal until you try and exit the shell with ^Z or ^D.
mci.c:1332: GetLastError: 1
mcishell: 12 tests executed (0 marked as todo, 1 failure), 0 skipped.

But the program does not exit.  Hitting ^C leads to:
fixme:console:CONSOLE_DefaultHandler Terminating process 8 on event 0
err:ntdll:RtlpWaitForCriticalSection section 0x7efec8e4 "loader.c:
loader_section" wait timed out in thread 002a, blocked by 0009, retrying (60
sec)
err:ntdll:RtlpWaitForCriticalSection section 0x7eecc1c0 "console.c:
CONSOLE_CritSect" wait timed out in thread 002b, blocked by 002a, retrying (60
sec)
...
Process of pid=0008 has terminated
No process loaded, cannot execute 'echo Modules:'
Cannot get info on module while no process is loaded
No process loaded, cannot execute 'echo Threads:'

Bug #28042 too is about loader.c deadlocks. But here it's at exit, not DllMain
start.

Note that for the bug to trigger it seems essential to "play ri from 0 notify"
once successfully.
