listener: ignore_eof_count must be volatile.

* parser.c (repl): Due to the longjmp-like non-local control
transfers taking place, ignore_eof_count must be volatile.
The reason is that we change it after saving the context,
and then examine it after catching an exception. I'm seeing it
have a bad value after an exception is caught, resulting in
the ** EOF ignored by user preference" even though I
configured an integer value.
