--- Comment #1 from Adam Butcher <adam at jessamine dot co.uk> ---
The same ICE occurs without the use of 'auto'. Modifying the testcase from
template<typename T, auto, int = 0> void foo(T, auto) {}
to either
template<typename T, float, int = 0> void foo(T, auto) {}
or
template<typename T, float, int = 0, typename X> void foo(T, X) {}
causes the same backtrace. The default 0 for the int parm is also not
significant. The ICE seems to be caused whenever an error_mark_node is left in
the template parameter list for whatever reason. Looks like 4.8 used to bail
early in that case ("confused by earlier errors, bailing out").
