The following invalid code snippet triggers an ICE on mainline:

==============================================
template<int... N> void foo()
{
  sizeof...N();
}

void bar()
{
  foo<0>();
}
==============================================

bug1.cc: In function 'void foo()':
bug1.cc:3: error: 'N' cannot be used as a function
bug1.cc: In function 'void foo() [with int N = #'argument_pack_select' not
supported by dump_expr#<expression error>]':
bug1.cc:8:   instantiated from here
bug1.cc:3: error: '0' cannot be used as a function
bug1.cc:3: internal compiler error: tree check: expected tree_vec, have
error_mark in tsubst_copy_and_build, at cp/pt.c:10528
Please submit a full bug report, [etc.]

The broken diagnostic "'argument_pack_select' not supported by dump_expr"
is already tracked in PR33118.
