test case
Following example gives as assertion failure since
https://github.com/llvm/llvm-project/commit/913f6005669cfb
Interestingly there are several bugzillas with same assertion failure, but they
are all fixed long back, so this is a new issue.
$ cat b4.cpp
class A{};
class C;
class C: public A{};
class D: public C {
public:
int S(int);
};
typedef int(A::*F)(int);
auto x = (F)&D::S;
$ clang -c b4.cpp
clang:
/home/sunil/CLANG-GIT/llvm-project/clang/include/clang/AST/RecordLayout.h:251:
clang::CharUnits clang::ASTRecordLayout::getBaseClassOffset(const
clang::CXXRecordDecl*) const: Assertion `CXXInfo->BaseOffsets.count(Base) &&
"Did not find base!"' failed.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace, preprocessed source, and associated run script.
