Does this warning hint at something like a dangling reference that
should be fixed, or can it be safely ignored?
It's warning you that you're recursively calling the SIGCHLD trap handler.
It's clearer when the debugging messages are enabled:
Could the message be reworded to mention that explicitly?
line 2: warning: SIGCHLD trap handled called recursively
