bug#24358: 25.1.50; re-search-forward errors with "Variable binding depth exceeds max-specpdl-size"

[Sam Halliday]

when I build emacs-25 with this patch (either by building emacs-25
directly or taking emacs-25.1 and applying this patch) I get a failure
in make:

./autogen.sh
CFLAGS='-O0 -g3 -gdwarf-4' ./configure --enable-checking='yes,glyphs' 
--enable-check-lisp-object-type --prefix=/opt/emacs25
make
