It might be that App::Stacktrace doesn't work with Coro. Or it might just be some other reason it doesn't work in your particular environment.

The documentation for App::Stacktrace immediately mentions three options. If one were actually curious about what was going on, every one of those three options looks like something one would try.

This is debug by strace last calls:

rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0
rt_sigaction(SIGCHLD, NULL, {SIG_DFL, [], 0}, 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
nanosleep({1211417888, 0}, {1211354002, 168413065}) = ? ERESTART_RESTA
+RTBLOCK (To be restarted)
--- SIGWINCH (Window changed) @ 0 (0) ---
restart_syscall(<... resuming interrupted call ...>) = ? ERESTART_REST
+ARTBLOCK (To be restarted)
--- SIGWINCH (Window changed) @ 0 (0) ---
restart_syscall(<... resuming interrupted call ...>

What does that mean? What to look for? Something with thread sor ...? There is a usleep command after my coro-using function to sleep, and as i see there's a work after thread execution and then there's a usleep, so it's the last in trace (nanosleep ...)
