rpclib crashes when client closes connection #161
Description
I updated rpclib to commit 9885c01 and have started seeing this issue in AirSim. Whenever client closes connection (while rpc server is still executing the last request), the rpc server is crashing. I'm running rpc server in in async mode with 4 threads.
Exception message
Exception thrown at 0x00007FFB05EC445D (ntdll.dll) in UE4Editor.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF.
