This is still reducing, well I got distracted for a little bit also.

Reduced testcase:
template< typename T> struct has_begin {static const bool value =0;};
template<bool a> struct sequence_tag_impl{};
template< typename Sequence>
struct sequence_tag  : sequence_tag_impl<has_begin<Sequence>::value >{};
template<typename T>struct lambda{};
template<template< typename P1 > class F, typename T1 >struct lambda<F< T1 >
>{};
template< typename Tag >struct size_impl;
template<typename Tag, long Arity = size_impl< typename sequence_tag<Tag>::type
>::value>
    struct basic_expr{};
int main()
{
     lambda<basic_expr<short, 2> > a;
}

------

This looks like it was caused by an extension which was removed in 4.2.0.
Also I think there might be a dup of this bug filed already.

That would be PR 28088.
