dyung added a comment.
If it helps, I have so far been able to reduce the file to this which still
shows the failure when compiled with gcc 7.5:
#include "ASTPrint.h"
#include "clang/AST/ASTContext.h"
#include "clang/ASTMatchers/ASTMatchFinder.h"

}
When compiled with gcc 7.5, it produces the attached (gzip'd) assembly file
which is what is what is giving the errors:
GNU assembler version 2.30 (x86_64-linux-gnu) using BFD version (GNU Binutils
for Ubuntu) 2.30
