该进程在 Windows 7 中不稳定地崩溃。我使用!analyze -v
命令 inWinDbg
进行异常分析。它告诉以下信息。异常实际上是由WaitForSingleObject
调用的函数抛出的IrsSim!IrsNet_BlockOutput
。WinDbg 的异常分析告诉我这是INVALID_POINTER_READ
错误的。
对于调用代码,pChannel->hMutex
is not NULL
。我已经倾倒它并检查了它的价值。
IRSNETRET IrsNet_BlockOutput( IRSNET *pChannel)
{
// Check channel
IRSNET_CHECK_CHANNEL(pChannel);
// Wait for synchronization mutex
switch(WaitForSingleObject(pChannel->hMutex, INFINITE))
{
...
}

之后,我使用 !teb 命令尝试获取更多堆栈信息。
