The following valid code snippet triggers an ICE since GCC 4.1.0:
=============================
template<int> void foo()
{
int i = (int) { 0 };
}
template void foo<0>();
=============================
bug.cc: In function 'void foo() [with int <anonymous> = 0]':
bug.cc:6: instantiated from here
bug.cc:3: internal compiler error: in tsubst_copy, at cp/pt.c:8342
Please submit a full bug report, [etc.]

------- Comment #1 from pinskia at gcc dot gnu dot org 2007-03-04 22:00 -------
I can fix the testcase here by optimizing when we produce a CLEANUP_POINT_EXPR
but the following testcase still fails at that point:
int f(void);
template<int> void foo()
{
int i = (int) { f() };
}
template void foo<0>();

#8 0x0017dc54 in cp_parser_initializer_clause (parser=0x434e1dc0,
non_constant_p=0xbffff039 "") at ../../gcc/cp/parser.c:12954
12954 initializer = fold_non_dependent_expr (initializer);
And fold_non_dependent_expr sets processing_template_decl to false.

------- Comment #6 from pinskia at gcc dot gnu dot org 2008-05-28 23:54 -------
What caused this regression was the change of representation of CONSTRUCTOR. I
can make this easy work with a simple patch which looks at values of the
CONSTRUCTOR.
