scope
Classification: Unclassified

Version: 4.7.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++

This is a recent gcc-4_7-branch regression.
The case builds with trunk (r197936), fails with 4.7 branch (r197941):
struct A
{
A (int);
};
template < typename >
void Fn ()
{
const int kCapacity = 0;
struct Q:A
{
Q ():A (kCapacity) { }
};
Q q;
}
template void Fn < int >();
$ trunk/bin/g++ -c t.cc && echo ok
ok
$ 4.7/bin/g++ -c t.cc
t.cc: In instantiation of ‘Fn()::Q::Q() [with <template-parameter-1-1> = int]’:
t.cc:14:7: required from ‘void Fn() [with <template-parameter-1-1> = int]’
t.cc:16:26: required from here
t.cc:12:26: error: ‘kCapacity’ was not declared in this scope
