I normally quit clang-query, or pretty much any other interactive command line

this works on Windows 10 I'd rather users do it that way. We can make this more
discoverable through documentation.

Hi Richard, it looks like this commit caused an assertion failure on the
following input:
$ cat test2.ii
# 2 "" 3
namespace a {
enum { b };
}
template void c() {
auto d = [](auto) {
using a::b;
b;
};
d(0);
}
void e() { c; }
$ clang test2.ii
clang: ../clang/lib/Sema/SemaTemplateInsta
FWIW, I don't think you actually need the if.

The word "hosted" takes its meaning from the C/C++ standards. It refers to a

Perhaps it would be better to enable -ffunction-sections/-fdata-sections
unconditionally at the linker level if the linker supports it? See also PR22999.

It seems to me that this sanitizer would break the semantics of otherwise
well-defined programs. For example:
int *x = nullptr;
delete x;
if (x != nullptr) {
// normally unreachable
}
It may be that a null comparison would be enough
