Right. That's what I do when I want the signal to be propagate.
I don't know if this is what is happening but, unfortunately, gdb only
understands windows signals. Physically pressing CTRL-C is an event
which gdb will recognize as a "SIGINT". Sending the process a SIGINT
via "kill" or some other method will not be recognized by gdb.
