One was alltraps_with_regs_pushed, the other was calltrap. When the stack tracer walks up, it looks for magic symbol names to determine how to parse non-standard stack frames, such as a trapframe. It was looking for "calltrap". Which of the two symbols you got depended on things like Phase of moon, etc. If you were unlucky, you got a garbage stack trace for things like 'debug.trace_on_panic', which would completely hide the actual source of the problem.
