Bug #: 53360
Summary: Problems with -std=gnu++0x
Classification: Unclassified
Product: gcc
Version: 4.6.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
I have such code:
template<class CppType>
struct make_literal;
template<>
struct make_literal<int> {
typedef int type;
};
template<class T>
struct make_expression {
typedef typename make_literal<T>::type type;
};
struct column {
template<class T>
typename make_expression<T>::type operator= (const T& t) const {
return typename make_expression<T>::type(t);
}
};
struct expression : column
{
expression() { }
using column::operator =;
};
int main()
{
expression ex;
ex = 2;
return 0;
}
which failed to compile with such command line:
c++ -std=gnu++0x file.cpp
Compiler produces such error:
bug.cpp: In instantiation of ‘make_expression<column>’:
bug.cpp:31:10: instantiated from here
bug.cpp:12:42: error: invalid use of incomplete type ‘struct
make_literal<column>’
bug.cpp:3:8: error: declaration of ‘struct make_literal<column>’
