Summary: Bug in Sysexhandling of winealsa.drv
           Product: Wine
           Version: unspecified
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-multimedia
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When adding sysex buffers using midAddBuffer, the MHDR_INQUEUE flag is not
set in the lpMidiHdr->dwFlags.
This results in reaper (www.reaper.fm) completely freezes the machine when
trying to add sysex buffers (because it apparently checks the dwFlags Field of
the buffers it tries to add and will continuously add them to the bufferlist 
until all memory is exhausted).

A fix is to add following line in
dlls/winealsa.drv/midi.c, function midAddBuffer:

EnterCriticalSection(&crit_sect);
lpMidiHdr->dwFlags |= MHDR_INQUEUE;           <<<< add this line
if (MidiInDev[wDevID].lpQueueHdr == 0) {
