Bug #: 54442
Summary: Const overloads resolution failure
Classification: Unclassified
Product: gcc
Version: 4.7.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: nikkoara@hates.ms
gcc fails to take address of const overloads, possibly confused by the index_t
typedef:
$ gcc -v; cat t.cpp; gcc -c t.cpp
Using built-in specs.

For gcc 4.8.0 20120819 (experimental) I'm getting an ICE instead:
"20|internal compiler error: canonical types differ for identical types
void(index_t)__attribute__((const)) {aka void(int)__attribute__((const)) throw
()} and void(int)__attribute__((const)) throw ()"

"using" and "extern"C"" are not guilty:
struct S
{
void s (int) const throw ();
void s (int) throw ();
};
typedef int index_t;
void (S::*f) (index_t) = &S::s;
void (S::*g) (index_t) const = &S::s;
The bogus pretty printing with attribute((const)) is PR 48665.

I guess this should be closed as fixed, unless this will be backported to 4.9?
