Subject: bug#53680: Endless loop in peculiar case of string-match and string-match-p 27.02 and 28.0.50
Date: Tue, 1 Feb 2022 08:37:37 +0100 [thread overview]
Message-ID: <183c66f4-463a-b372-feee-5af9f6f45719@cvj.se> (raw)
Hello
Some context first, since I needed a multi-line regexp matcher that
could tell the difference of end-of-string vs newline ($ vs \n) in a
string I replace occurrences of \n with \r in a string.
In a peculiar case a endless loop happens and I can reproduce this bug
in Emacs 27.2 and 28.0.50 (have not tested any other versions), ok try
to eval following snippet:
(string-match-p·"[\r\t·]*implements[\r\t·]+\\([\r\t·]*[\\a-zA-Z_0-9_]+,?\\)+[\r\t·]*{$"·"ariable·implements·\\Magento\\Framework\\Event\\OberserverInterface\r{\r····public·function·__construct()\r·")
or
(string-match·"[\r\t·]*implements[\r\t·]+\\([\r\t·]*[\\a-zA-Z_0-9_]+,?\\)+[\r\t·]*{$"·"ariable·implements·\\Magento\\Framework\\Event\\OberserverInterface\r{\r····public·function·__construct()\r·")

Hälsningar / Best Regards
Christian
