Emulator breaks with compiler optimizations (-O3) #193

bo3z commented 4 months ago

This is not an issue in ACCL and there is no known fix as of yet, but I am opening this issue for anyone encountering it in the future.

Namely, when the emulator is compiled (CMakeLists.txt) with compiler optimizations (-O3), it can produce very weird behaviour, causing streams to be stuck and the program never to terminate.
