Bug ID: 65406
Summary: Wrong namespace in error message for missing
"typename" in lambda parameter type list
Product: gcc
Version: 4.9.1
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: arvo at me dot com
Simplified source (compile with -std=c++11):
namespace not_here
{
template<typename T>
struct Buzz;
} // namespace not_here
namespace here
{
template<typename T>
struct Foo
{
typedef not_here::Buzz<T> Bar;
void bad_error();
};
} // namespace here
template<typename T>
void here::Foo<T>::bad_error()
{
[](/*typename*/ Bar::type){};
}
This produces the following error message:
missing_typename_bad_error.cxx: In member function ‘void
here::Foo<T>::bad_error()’:
missing_typename_bad_error.cxx:21:26: error: ‘not_here::Bar<T>::type’ is not a
type
[](/*typename*/ Bar::type){};
Note that the qualified name for Bar is "here::Foo<T>::Bar" and not
"not_here::Bar". Also, Bar is not a template. So far I have only been able to
reproduce this with a parameter-type-list in a lambda expression, more logical
and helpful error messages are given e.g. for parameter-type-lists for function
types and for the attempt to create a local variable.
Observed in GCC 4.8.1 and 4.9.1 on openSUSE 13.1 (x86_64)
