Using both 4.2 and 4.3, I can reproduce a segfault on completion (though
not using gdb)

This can happen very consistently using a time-consuming completion like
the one for `man`, eg:
$ man g<tab><tab>^C

Attached is the trace from a core-file using `man gpg-agent g<tab><tab>^C`
with bash 4.3.

Side note: as more and more completions take time to finish (think ssh,
dpkg, ...), having ^G to interrupt the completion process and not having
to use ^C which discard the whole line could be useful.
From quick look I see missing memory allocation and probably dislocation.
