Bug ID: 24123
Summary: Using declaration
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
Consider the following program:
namespace N {
extern int x;
}
int main() {
using N::x;
extern int x;
}
Compiling it gives the following error output (i have tried with trunk 242150):
7:16: error: declaration conflicts with target of using declaration already in
scope
extern int x;
^
2:16: note: target of using declaration
extern int x;
^
6:14: note: using declaration
using N::x;
^
For comparison I tried it with GCC also (trunc 201507) and got no errors. I
think that is the correct behaviour, but it could be that GCC is wrong or that
this is an ambiguity in the c++ standard.
