This is Emacs built from master after the concurrency branch was merged.
Evaluating the expression
(make-thread #'gnus "gnus")
crashes Emacs and causes the emacs process to disappear. Note: This does
not happen always -- I've gotten it to run successfully a couple of
times, but crashes more often than not.
In GNU Emacs 26.0.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.10.8)

Thanks, I think I fixed this now.

Your original recipe doesn't crash for me anymore with the current
trunk. I tried on 2 different systems.
If someone sees a crash, please post a backtrace.

When the crash happens for me, the entire emacs disappears -- I suspect
it has to be run inside GDB --- but that is going to be hard for me to
do since I lose all speech output when emacs dies.

The original problem was not a crash, it was an abort. I guess what
you describe still happening to you is also an abort.
If someone else can reproduce this and show a backtrace, maybe I'll
have an idea.

This log may give you some more info.
I placed the expression
(make-thread #'gnus "gnus")
in a file "g.el" , then started emacs like so:
emacs -l g.el & from an XTErm.
That started successfuly and even started gnus.
Then I evaluated the same expression in the minibuffer and that emacs
aborted.
i then grabbed the log output to that XTerm -- here's what it says:
In case it matters, I'm using stumpwm as my window manager, not gnome.

This error message sounds like what Ken Raeburn fixed in [1] (more
context in [2]). Does this bug still occur in latest master?
