interrupt_signal is a signal handler. How did you stop Emacs?
Did you do it by typing a command at Emacs? That is dumb -- it will
interfere with what happens inside Emacs. You should stop Emacs by
going to the window where GDB is running, and typing C-z.
Anyway, it looks like GDB has a bug in returning from signal handler
commands with `finish'. Please report the GDB bug, because we need to
get it fixed.
Meanwhile, you probably CAN proceed from this. Just use the `up' command
to select the containing frame, and type `finish' in that one.
If you get to an ordinary (non-signal-handler) frame this way,
`finish' should work on it.
