Bug #: 55338
Summary: Incorrectly reported error in type name hiding
Classification: Unclassified
Product: gcc
Version: 4.7.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: piotr.wyderski@gmail.com
The following snippet:
class A {};
class B : public A {
typedef A super;
public:
class X {};
};
class C : public B {
typedef B super;
class X : public super::X {
typedef super::X super;
};
};
compiles without a warning on Comeau and MSVC, but GCC (4.6.1 and
4.7.1) failes with the following message:
$ gcc -c bug.cpp
bug.cpp:18:24: error: declaration of ‘typedef class B::X C::X::super’
[-fpermissive]
bug.cpp:14:14: error: changes meaning of ‘super’ from ‘typedef class B
C::super’ [-fpermissive]
To my understanding of the Standard Comeau is right and GCC is wrong here.
