Are you running the Ruby interpreter from inside a signal handler ? If so, 
don't do that :-) The signal handler has its own environment (the original 
environment had to be saved so you return to the exact location after handling 
the signal). One may only call async-safe functions inside signal handlers, 
for a list see the following page (scroll down to the end):

You would need to find another way to respond to the signal, like setting a 
variable and periodically check for it in your main loop or something like 
that.
