Subject: bug#25451: 24.5; Freeze after while-keyword in sh-mode
Date: Sat, 14 Jan 2017 21:54:41 +0100 [thread overview]
Message-ID: <905d96c6-951c-ca3c-cedf-cbdfc2cb34d6@tamagothi.de> (raw)

While typing the following, rather ordinary shell script in sh-mode,
Emacs freezes and consumes full CPU. I had to kill the process.

The bug is fully reproducible after recover-this-buffer.
In text-mode, the bug does not occur.
If the 'while' is part of a complete loop 'while :; do something; done;
the bug does not occur.
I guess, it is a bug in sh-mode, but reading LISP is hard for me, so I
did not investigate further.
