Subject: bug#46797: mac_font_shape EXC_BAD_ACCESS
Date: Sat, 27 Feb 2021 05:07:31 +0000 [thread overview]
Message-ID: <CAKDRQS5sJxiXUgOJQgsnSwM3R7D7YO8=vB7oG+_CY8ZcjwB25A@mail.gmail.com> (raw)
In-Reply-To: <YDlGDV1FPebgMBQZ@breton.holly.idiocy.org>
All I did was type really fast under emacs-lisp-mode that has company
and company-box setup, I just typed faster than company was able to
show me a completion menu.
Like many emacs crashes and hangs, I have no way of reproducing them
consistently. Given there's not even an lldbinit written, I can't even
debug it effectively. All I can do is run emacs compiled with
debugging information under lldb.
