As far as I can tell, the problem actually seems to be 24.3 specific,
so yes, assuming you meant <=24 rather than <24. In 24.3, the
following triggers an error when run interactively, but there is no
error in --batch mode, or when using with-temp-buffer (this is a
reduction from yasnippet's example-for-issue-474 test). That was the
motivation for adding yas--with-font-locked-temp-buffer (and I just
threw it in for all cc-mode related tests, just in case).
(setq debug-on-error t)
(with-current-buffer (get-buffer-create "foo") ;with-temp-buffer
(c-mode)
(insert "#include <foo>\n")
(narrow-to-region (point) (point))
(insert "`\"TODO: \"`")
(delete-region (point-min) (point-max))
(insert "TODO: "))
