Summary: [C++0X] ICE on invalid: in register_constexpr_fundef,
at cp/semantics.c:5571
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: marc.glisse@normalesup.org
This is an ICE on invalid code that I hit while trying to reduce an example for
a more important bug.
extern "C" {
enum A { };
inline constexpr A
f(A a, A b)
{ return A(static_cast<int>(a) & static_cast<int>(b)); }
enum B { };
inline constexpr B
f(B a, B b)
{ return B(static_cast<int>(a) & static_cast<int>(b)); }
}
4.cc: In function ‘constexpr B f(B, B)’:
4.cc:8:13: error: declaration of C function ‘constexpr B f(B, B)’ conflicts
with
4.cc:4:3: error: previous declaration ‘constexpr A f(A, A)’ here
4.cc: In function ‘constexpr B f(B, B)’:
4.cc:9:58: internal compiler error: in register_constexpr_fundef, at
cp/semantics.c:5571
