[Message part 1 (text/plain, inline)]
Hi all,
I usually use Emacs 27 (AKA `master`). I upgraded to the latest Mojave
beta (1 week until GM I believe, I was eager!)
Thanks Alan for providing the patch, I took the patch (which you said
was based on emacs-26) and "updated"
(used the `wiggle` command for the hunks that wouldn't apply, I've never
really meddled with Objective-C before and
I've never really updated a patch before when there's rejected hunks, so
please excuse any ignorance you pick up on. :-)
The patch builds and launches Emacs successfully! (Thanks again Alan)
However, just thought I'd mention that after some time (5-10 minutes of
idling, and just now it crashed during launch) I get the following:
Note that I *believe* I've compiled Emacs with debugging symbols and no
optimisation, feel free to correct me if not.
Hopefully the below output is helpful to someone. This might even be a
bug in Mojave and one of the core libraries, but I haven't had
this with other applications:
I can reproduce the issue within a maximum of 10 minutes, whether typing
or not.
It's likely worthy to note that this happened also with the emacs-26
branch, commit d4fa83baf5462cfcf61ebbb8c0a0ec584d11c39a,
under the same circumstances, and with the attached patch applied.
Feel free to shout at me to submit this as a new bug, I couldn't find
which email makes a new one. :-(
The below happens on commit 75d9a55fae1c484aa6d213064931bfe3b65cf5dd on
the master branch.
