Bug ID: 15558
Summary: False positive for -Wunused-variable with static
member of internal-linkage type
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
$ cat test.cc
namespace {
class Bar {};
}
class Foo {
static Bar b;
};
$ clang -fsyntax-only -Wunused-variable test.cc
test.cc:5:14: warning: unused variable 'b' [-Wunused-variable]
static Bar b;
^
In the actual code I found this in, 'Foo' and 'Bar' are defined in foo.h, which
is included into both foo.cc, which uses 'b', and foo_test.cc, which doesn't
use 'b'; we produce a warning when compiling foo_test.cc.
