Bug ID: 52420
Summary: Clang fails to compile valid template for
x86_64-pc-windows-msvc target
Product: clang
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: [email protected]
Reporter: [email protected]

Originally reported by Anthony Erlinger:
The following valid code fails to compile with -target x86_64-pc-windows-msvc:
template <typename A>
struct S {
void f() {
const int B = 5;
struct C {
int g() {
return B; // <-- error: use of undeclared identifier 'B'
}
};
}
};
void test() {
S<int>().f();
}
Invocation: clang -target x86_64-pc-windows-msvc example.cc
Compiler output:
<source>:7:24: error: use of undeclared identifier 'B'
return B;
^
<source>:14:14: note: in instantiation of member function 'S<int>::f' requested
here
S<int>().f();
1 error generated.
Compiler returned: 1
Godbolt example showing failure in clang vs successful compile in MSVC:
https://godbolt.org/z/h6431Wbh5
This is fixed with the flags /Zc:twoPhase or -fno-delayed-template-parsing, but
works in MSVC itself, so it's clearly a bug in how we emulate MSVC's
non-compliant template instantiation.
