Pre-processed source file and run-script related to the crash

I am not very knowledgeable how Clang works and thus I am unable to give any
hints what exactly went wrong.

Attached are the pre-processed source and run-script.

clang version 7.0.0
Target: x86_64-portbld-freebsd11.1
Thread model: posix
InstalledDir: /usr/local/llvm-devel/bin

And here is the crash backtrace:

Assertion failed: (Info.Ctx.hasSameType(BaseIt->getType(), BaseType) && "base
class initializers not in expected order"), function HandleConstructorCall,
