Summary: g++ sometimes incorrectly allows copying a volatile
trivially-copyable class
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: jason@gcc.gnu.org
As noticed in PR 48113, we fail to give an error for the call to f below even
though it involves copying a volatile object and A doesn't have a copy
constructor that allows a volatile argument.
struct A { };
void f (A);
void (*g)(A);
int main()
{
volatile A a;
f(a);
g(a);
}

Fixed for 4.7. Might backport to 4.6.1 (along with the two other patches) if
no problems turn up.
