Bug ID: 27066
Summary: [ms] __declspec(dllexport) causes redefinition with
same mangled name as another definition
Product: clang
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: andrey.kules...@intel.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
!- This problem is related to dllexport. MSVC compiles sample described below.
Note that even if clang's behavior is correct, compiler's diagnostic is not
usable:
error: definition with same mangled name as another definition
class A {}; (why class A is redefined?)
note: previous definition is here: <no line> (where is the line with the
previous definition?) -!
==========Small Reproducer==============
typedef struct _GUID { int i; } ID;
template <const ID* piid>
class A {};
struct
__declspec(uuid("{00000000-0000-0000-c000-000000000046}"))
S1 {};
struct
__declspec(uuid("{00000000-0000-0000-c000-000000000046}"))
S2 {};
struct __declspec(dllexport)
C1 : public A <&__uuidof(S1)>
{};
struct __declspec(dllexport)
C2 : public A<&__uuidof(S2)>
{};
==============Error=====================
>>>clang:
test.cpp(4,7) : error: definition with same mangled name as another definition
class A {};
^
test.cpp(4,7) : note: previous definition is here
1 error generated.
>>>MSVC:
