It seems that the compiler tries to skip instructions that are
not locked with a `writeln()` or something similar. Usually I
can safely remove the writeln after compiling it once with that
way. However I've once ran into an issue when a previously
working code just started to emit random junk data depending on
CPU usage, and in that case the aforementioned workaround only
partially worked (delaying crashes, etc).
I've heard something about Mutex, however I lack the experience
with multithreading.
Is there public code you can link to ?
Look for any usage of `__gshared`. Are you using `shared` as well
? Turn on `-preview=nosharedaccess` to get better diagnostic. Are
you using any `extern` code ? How do you communicate between
threads ? Message passing, or simple shared memory ?
