Summary: ICE with int templates

Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: c++
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: weiss at sztaki dot hu

The following example causes an ICE:
gonzo:~ # cat foo.cc
template <int A, int B, int C, bool D=(A<B)>
struct a
{
enum { value = D? A+B: A+C };
};
template <int A>
struct b
{
// enum { value = a<A,A,A>::value }; // compiles
// enum { value = a<A,1,A>::value }; // compiles as well
// enum { value = a<1,A,A>::value }; // compiles as well
enum { value = a<1,1,A>::value }; // ICE
};
int main()
{
return b<1>::value;
}

2003-07-08 Mark Mitchell <mark@codesourcery.com>
* fold-const.c (make_range): Do not access operand 1 for a
zero-operand operator.
--- gcc/gcc/cp/ChangeLog ---
2003-07-08 Mark Mitchell <mark@codesourcery.com>
* cp-tree.def (NON_DEPENDENT_EXPR): New node.
* cp-tree.h (build_call_from_tree): Remove.
(build_member_call): Likewise.
(dependent_template_arg_p): Remove.
(any_dependent_template_arguments_p): New function.

(any_type_dependent_arguments_p): Likewise.

The regression hunt took place on i686-pc-linux-gnu and used the
submitter's test case.
