Ugh, I left cvise running overnight and forgot to include the validity check by
building with a previous clang, so my reduction is invalid. I'm going to run it
again, but here's the invalid crasher in the meantime:
struct SourceLocation {
static SourceLocation current(const char * = __builtin_FILE()) {
struct Metadata {
Metadata(SourceLocation = current());
namespace struct {
int x = z(x, Metadata())
} y {
}
stack trace:
clang: /home/rupprecht/src/llvm-project/clang/include/clang/AST/Type.h:752:
const ExtQualsTypeCommonBase *clang::QualType::getCommonPtr() const: Assertion
`!isNull() && "Cannot retrieve a NULL type pointer"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/
and include the crash backtrace, preprocessed source, and associated run script.
