Bug #: 56697
Summary: Erroneous rejection of use of private constructor in
public method
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: n...@cam.ac.uk
What I believe is an erroneous rejection of a program. Unfortunately, the
C++ standard is too contorted in this area for me to be absolutely sure,
Anyway, Intel is happy with it.

class weeble {
public:
weeble () {}
class wurble {
int n;
wurble (int k) : n(k) {}
public:
wurble () : n(0) {}
};
wurble fred (int k) {return wurble(k);}
};
int main () {
weeble a;
weeble::wurble b = a.fred(42);
}
