From: Ernesto Alfonso <erjoalgo <at> gmail.com> To: 23667 <at> debbugs.gnu.org Subject: bug#23667: 24.4; "Stack overflow in regexp matcher" happens in only some buffers, for the same arguments Date: Tue, 31 May 2016 19:41:20 -0700
(let ((out (shell-command-to-string "curl http://pastebin.com/raw/a2pMaW6h"))) (string-match "\\(^[[:space:]]*\\([a-z]+\\) = \\(.*\\)\n\\)+" out 0)) If I try this sexp on an ielm-mode or emacs-lisp-mode buffer (just two examples I tested), this evaluates to 0. If I try it on a message-mode or erc buffer, I get "Stack overflow in regexp matcher". The evaluation should be independent of the buffer since no buffer contents should be involved.
