In winnt_accept() (server/mpm/winnt/child.c), there's a call to PostQueuedCompletionS...

When compiling the code with Visual Studio 2019 (v 16.3.10), we get a warning than BytesRead is not initialized. When using /RTCu (run-time checks for uninitialzed variables), the program crashes on this line with an exception.

If we initialize the variable to 0, the problem is solved.
