Re: c-mode imenu: Stack overflow in regexp matcher

[Glenn Morris]

I've reduced the problem to a regexp search called from:

(imenu--generic-function imenu-generic-expression)

Evaluating the following in a buffer visiting splash.xpm as text
causes a stack overflow in the regexp matcher:

  (goto-char (point-max))
  (re-search-backward 
"^\\<[^()]*[^[:alnum:]_:<>~]\\([[:alpha:]_][[:alnum:]_:<>~]*\\)\\([       
\n]\\|\\\\\n\\)*(\\([   \n]\\|\\\\\n\\)*\\([^   \n(*][^)]*\\)?)\\([     
\n]\\|\\\\\n\\)*[^      \n;(]" nil t ))


A 32-bit version works fine on x86_64, but the 64-bit version has the
problem.
