[Blake McBride]

Any ideas on a next step for this?

Thanks!

Hi,

so the last we see in Input.cc is:

*prompt:             '      ' at Input.cc:223

and then we call start_input(). That is a callback installed by emacs_mode.
We do not see that the next line is reached, so the segfault is most likely
thrown by start_input().

You could add Q((const void *)start_input) after line 223, but I doubt that this
will teach us anything new.

I guess Elias should have a look (maybe stale start_input() ?).

Hi,

ok, we are getting closer. Can you please replace Input.,cc with the attached
file and sent the output before the SEGFAULT (last 30 lines suffice)
