Bug ID: 45236
Summary: clang crashes in AST/CanonicalType.h:641
Product: clang
Version: 10.0
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend

Hi, please consider the following piece of code. Clang falls to compile, while
gcc successfully without any issue.
$ cat s.C
template <typename T, int N>
using V [[gnu::vector_size (sizeof (T) * N)]] = T;
void *foo ();
template <typename T, int N>
__attribute__((noipa)) void
test ()
{
V<T, N> *x = (V<T, N> *) foo ();
}
$ clang++ -c -std=c++11 s.C
s.C:7:16: warning: unknown attribute 'noipa' ignored [-Wunknown-attributes]
__attribute__((noipa)) void
^
clang-9:
/home/oscar/compiler/llvm-project/clang/include/clang/AST/CanonicalType.h:641:
