Bug #: 54653
Summary: [4.6/4.7/4.8 Regression] tsubst_template_parms ICE
Classification: Unclassified
Product: gcc
Version: 4.7.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: jakub@gcc.gnu.org
union A {};
struct B
{
template <class T> struct C {};
};
template <class F, template <class T> class D = B::template C>
struct E;
template <typename R, template <class T> class D>
struct E <R (), D>
{
void (*f) (A &);
template <class I, template <class T> class J>
struct G { static void d (A &); };
template <class H> inline E (H &fn)
{
f = &(G <H, D>::d);
}
};
template <typename R, template <class T> class D>
struct E <R (), D>::G <R (*) (), D>
{
};
struct Z { int z; };
int
main ()
{
Z t = {};
E <int ()> f (t);
}
ICEs in tsubst_template_parms, because parms is NULL. The ICE started in
between r128000 and r128500.

--- Comment #4 from Jason Merrill <jason at gcc dot gnu.org> 2012-12-05 17:46:21 UTC ---
This code is actually ill-formed; the specialization
template <typename R, template <class T> class D>
struct E <R (), D>::G <R (*) (), D>
{
};
only has one template-header, and should have two. Furthermore, this is a full
specialization of a member of a partial specialization, which is not allowed.
14.8/16: "the declaration shall not explicitly specialize a class member
template if its enclosing class templates are not explicitly specialized as
well."
