<pre>I'm willing to believe it's an undname bug :-) The wine implementation of
_unDName has it too fwiw.
I tried finding the test case you mention but failed.
...aha, but here's a from-source repro that shows you're right:
$ cat test.cc
struct S {};
struct T {
static const S* s_;
const S* s();
void set(const S* s);
};
const S* T::s() { return s_; }
void T::set(const S* s) { s_ = s; }
$ third_party/llvm-build/Release+Asserts/bin/clang-cl /c test.cc /Fa -Xclang
-emit-llvm 2&>1 > /dev/null ; cat test.asm | grep s_
@"?s_@T@@2PEBUS@@EB" = external dso_local global %struct.S*, align 8
%0 = load %struct.S*, %struct.S** @"?s_@T@@2PEBUS@@EB", align 8
store %struct.S* %0, %struct.S** @"?s_@T@@2PEBUS@@EB", align 8
$ demumble '?s_@T@@2PEBUS@@EB' # currently uses wine _unDName()
public: static struct S const * __ptr64 const __ptr64 T::s_
$ bin/llvm-undname '?s_@T@@2PEBUS@@EB'
?s_@T@@2PEBUS@@EB
public: static struct S const *T::s_</pre>
