That's because `org-latex-regexps' is a bit too complex for Emacs regexp
engine in some cases. For some unfortunate Org files, these regexps may
trigger stack overflow while matching.

Eventually, we will switch to parser-based fontification, and the
problem will be solved.

For now, I have no clue how to simplify the problematic regexps without
risking regressions.
