Bug ID: 28676
Summary: -Wshadow doesn't warn on shadowed 'using' statements.
Gcc does.
Product: clang
Version: 3.8
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: xax...@gmail.com
CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
Classification: Unclassified
using Foo=int;
int i;
int main(){
using Foo=char; // <== clang doesn't warn about this, gcc does
int i;
}
gcc catches both: https://godbolt.org/g/6heXBO
clang 3.8 doesn't warn on the shadowed 'using': https://godbolt.org/g/zTgIDn
Tested with every version of clang on godbolt down to 3.3 (lower was broken)
and got the same behavior on each version of clang.
gcc seems to catch both on every version that supports c++11.
