The real problem is that sanitizer_print_stack_trace obtains current PC and expects the PC to be in the stack trace after function calls. We don't prevent tail calls in sanitizer runtimes, so this assumption does not necessary hold. We add "always inline" attribute on PrintCurrentStackSlow to address this issue, however this solution is not reliable enough, but unfortunately, we don't see any simple, reliable solution.
