Stefan, what am I missing?) font-lock.el has some `defsubst' (i.e. functions that get inlined) so the backtrace is "incomplete". The call to eval is actually in font-lock-apply-highlight or in font-lock-fontify-anchored-keywords (both inlined functions called from font-lock-fontify-keywords-region). If you load font-lock.el (i.e. the source code), the backtrace will be a lot more complete. Stefan
