            Bug ID: 57981
           Summary: 0758:err:virtual:virtual_setup_exception nested
                    exception on signal stack in thread 0758 addr

           Product: Wine
           Version: 7.0.2

debugging logs generated after running the application under Wine

My program uses WaitForMultipleObjects to monitor multiple pipes. It runs
normally in a Windows environment, but under Wine, after running for some time,
WaitForMultipleObjects stops working. When data is written to the pipe, it does
not return, and simultaneously, the Wine debug log reports the following error:
0758:err:virtual:virtual_setup_exception nested exception on signal stack in
thread 0758 addr 0x3f0003f4af stack 0x7fedf170
After that, it continuously prints the following log:
04b8:err:sync:RtlpWaitForCriticalSection section 0308D388 "?" wait timed out in
thread 04b8, blocked by 048c, retrying (60 sec)
01f8:err:sync:RtlpWaitForCriticalSection section 0308D388 "?" wait timed out in
thread 01f8, blocked by 048c, retrying (60 sec)

and this is my code:
while (true)
{
    DWORD dwWait = WaitForMultipleObjects(pPipeThread->chnNum + 1,    // number
of event objects 
        pPipeThread->hEvents,      // array of event objects 
        FALSE,        // does not wait for all 
        INFINITE);    // waits indefinitely 

    if (dwWait == WAIT_FAILED) 
    {
        DWORD dwError = GetLastError();
        char errorMsg[512];
        FormatMessageA(FORMAT_MESSAGE_FROM_SYSTEM |
FORMAT_MESSAGE_IGNORE_INSERTS,
            NULL, dwError, 0, errorMsg, sizeof(errorMsg), NULL);

        cerror("CPipeWrapper WaitForMultipleObjects failed, Error Code: %u,
Error Message: %s", dwError, errorMsg);
    }

    int i = dwWait - WAIT_OBJECT_0;  // determines which pipe 

    if (i < 0 || i > PIPE_NUM_PER_THREAD)
    {
        _dout("WaitForMultipleObjects threadidx(%d) chnNum(%d) Index out of
range(%d).", pPipeThread->threadIdx, pPipeThread->chnNum, i);
        continue;
    }

    if (i == 0)
    {
        if (CPipeMgr::Instance()->IsQuit())
        {
            _dout("PipeReadThread quit threadidx(%d) chnNum(%d)",
pPipeThread->threadIdx, pPipeThread->chnNum);
            return 0;
        }
        HandleChnCfgUpdate(pPipeThread);
        _dout("PipeReadThread config update threadidx(%d) chnNum(%d)",
pPipeThread->threadIdx, pPipeThread->chnNum);
        continue;
    }
    --i;
    unsigned int chnID = pPipeThread->chnIDs[i];
    CNamePipe* pPipe = CPipeMgr::Instance()->GetPipe(chnID);
    int rdLen = pPipe->GetOverlapReadedNum();
    int reminderLen = pPipe->GetReminderLen();
    if (rdLen > 0)
    {
        reminderLen = CMemDataMgr::Instance()->DecodeDrvData(chnID,
pPipe->GetReadedBuf(), reminderLen + rdLen);
    }
    int readed = 0;
    pPipe->ReadPipe(reminderLen, readed);
}
