In a really big project of mine, Clang seems to throw in ud2
instructions at some function calls. However, even with -Wall
it doesn't seem to tell me why. I am using coroutines quite heavily in that project, but the ud2
instructions end up at non-coroutine function calls.
Thanks in advance

Clang places ud2
instruction at whatever place that would be undefined behavior to reach. Doing this is not feasible.
