I am considering generating exceptions from within a signal handler to
clean up some error handling code. To make this work with g++, the
"-fnon-call-exceptions" option must be specified. What is the cost of
using this option wrt code size and runtime performance? I am assuming
there is some cost if an option must be specified to enable this, but I
don't know enough about how stack-unwinding and such is implemented to
guess how significant it may be.
thanks,
