Constant crashes when entering play mode #430

Open JetSimon opened 4 months ago

JetSimon commented 4 months ago

My Unreal editor crashes 1/3 of the time when entering play mode. I am using C++ but not native.

Points to https://github.com/getnamo/SocketIOClient-Unreal/blob/master/Source/SocketIOLib/Private/internal/sio_client_impl.cpp#L261 which is when the thread stops and reset gets called. Check your alloc/dealloc logic and compare vs how it's done for the component life cycle.

I'm seeing this error now, looks like a recent version broke it, use older plugin version for now until fix is found.

If it helps, I haven't had this issue occur since I stopped calling Disconnect and then Connect in the OnBegin (or whatever it is called) function of my socket actor c++ file. I think maybe a race condition there?
