Uh, in Emacs 24.5
(re-search-forward "\\[[^]]*\\<label" nil t)
throws the stack overflow error, indeed I tested also this
possibility. So are you saying that in Emacs 25.1 the noerror option
prevents stack overflow? Anyway, how about my suggestion to use
"\\[[^]]\{0,1000\}\\<label"
? 1000 characters are 12.5 80-column-wide lines, I think it's large enough.
Bye,
Mosè
