Subject: bug#42522: Emacs 27: 100% CPU when setting mode-name with ligatures
Date: Fri, 24 Jul 2020 14:35:50 -0700 [thread overview]
Message-ID: <CAEzBis6SRbk=7tAGA2Q7i+QU9=FoYbVOFti=SBLRztvz9rFSSA@mail.gmail.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 478 bytes --]
Emacs version: GNU Emacs 27.0.91 (build 1, x86_64-apple-darwin18.7.0, NS
appkit-1671.60 Version 10.14.6 (Build 18G5033)) of 2020-07-24
Built d5acc509415869bce22c49ae311f2960494a0bdc locally
To reproduce, evaluate this
(set-char-table-range composition-function-table 47
'([".\\(?:\\(?:\\*\\*\\|//\\|==\\)\\|[*/=>]\\)" 0 font-shape-gstring]))
And then evaluate
(setq mode-name "test//")
Emacs will become unresponsive and consume 100% CPU.
