The difference is 'type = int' vs. 'type = <type error>'.

--- Comment #1 from Jason Merrill <jason at gcc dot gnu.org> ---
This difference is caused by varpool_remove_node clobbering the DECL_INITIAL of
integral_constant<bool, false>::value, and then dump_template_bindings trying
to use the now clobbered value in printing out the name of a function.
It seems to me that varpool_remove_node shouldn't mess with variables that can
still be used for their value in constant expressions.
