Thus, Jason, it turns out this is *not* a duplicate of c++/38600, doesn't have
to do with mangling template_id_expr, right? By the way, if you have got two
spare minutes, could you maybe add something about the latter in that audit
trail? Duplicates are coming and coming, I'm afraid people (myself included ;)
are a bit confused about why we cannot mangle that.

I suspect this is the same issue, as it also passes a null argument to
write_expression

$ cat ice.cc
template
auto f(T t) -> decltype(++t, 0)
{
++t;
return 0;
}

int main()
{
f((int*)0);
}
$ ~/gcc/4.x/bin/g++ -std=c++0x ice.cc
ice.cc: In instantiation of 'decltype (((++ t), 0)) f(T) [with T = int*,
decltype (((++ t), 0)) = int]':
ice.cc:10:14:   instantiated from here
ice.cc:6:1: internal compiler error: Segmentation fault

Jason, the ICE happens in mangle.c, write_expression gets a null argument. Is
this another variant of c++/38600 and the likes?
