Bug ID: 46726
Summary: Clang rejects valid code with "anonymous types
declared in an anonymous union are an extension"
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: haoxi...@gmail.com

Hi, all.
This code, test.cc, is a valid code I guess, but Clang rejects this under
-pedantic-errors.
$cat test.cc
namespace g_namespace {
static union { union {} u; } ;
}
$clang++ -pedantic-errors test.cc
test.cc:2:21: error: anonymous types declared in an anonymous union are an
extension [-Werror,-Wnested-anon-types]
static union { union {} u; } ;
^
1 error generated.
Apparently, "union {} u;" is not an anonymous union.
While in other mainstream compilers, gcc, icc, or msvc, they all accept this
code.
Every Clang version from 4.0 onwards behaves the same (I didn't test anything
older).
Thanks,
Haoxin
