I have discovered that when using forkOS and exitWith that I get the following error: hud: internal error: scavenge_stack: weird activation record found on stack: 0 I have attached a relatively simple program that demonstrates the crash, here are steps to reproduce the crash: hud: internal error: scavenge_stack: weird activation record found on stack: 0
