Package: emacs24-nox
Version: 24.5+1-6+b1
Followup-For: Bug #810383
Dear Maintainer,
* What led up to the situation?
emacs hung up with 100% CPU usage while editing a bash script.
* What exactly did you do (or not do) that was effective (or
ineffective)?
1. Open the following bash script.
foo.sh
======
#!/bin/bash
if $# !=
awk -F, -f by_state.awk $*
======
NOTE: There is no "newline" at the end of this script.
2. Move a cursor to point to "i" at the beginning of line 3.
* What was the outcome of this action?
emacs hung up.
* What outcome did you expect instead?
emacs didn't hang up
* additional information
- The reproducibility is 100%.
- The backtrace is similar to what Sergey reported very much.
