我试图理解为什么我们的程序卡住了，有时候会崩溃。根据事件查看器，clr.dll是故障模型：
Faulting application name: MyProgram.exe, version: 0.0.0.0, time stamp: 0x54d4e6d4
Faulting module name: clr.dll, version: 4.0.30319.18444, time stamp: 0x52717f9a
Exception code: 0xc0000005
Fault offset: 0x00000000006eb320
Faulting process id: 0x5b94
Faulting application start time: 0x01d0423db66ac6e6
Faulting module path: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\clr.dll
Report Id: f70a46ad-ae30-11e4-b116-90e2ba482bf9
我使用了WinDbg并且我看到线程#0获得了锁并且正在等待线程#6使用的关键部分。
我注释掉了大部分代码。所以，现在c ++代码只在initGUI加载.Net CLR并调用open方法。 open方法只是启动空线程。
我从WinDbg添加了相关代码和线程信息。 我会欣赏任何方向。
