--- Comment #84 from John M. Drescher drescherjm@gmail.com 2009-01-07 18:00:42 --- I looked at the code for 0.9.24 and IOCP is not enabled:
HANDLE WINAPI CreateIoCompletionPort(HANDLE hFileHandle, HANDLE hExistingCompletionPort, ULONG_PTR CompletionKey, DWORD dwNumberOfConcurrentThreads) { FIXME("(%p, %p, %08lx, %08x): stub.\n", hFileHandle, hExistingCompletionPort, CompletionKey, dwNumberOfConcurrentThreads); SetLastError(ERROR_CALL_NOT_IMPLEMENTED); return NULL; }
It would be interesting to see what version added this function and see if that does indeed cause the crash.
