Thanks for the bug report!
I can reproduce it. The crash happens in the Clang's parser, i.e.
clang::ParseAST. On the other hand, I can't say it's a Clang bug because
apparently the Clang standalone doesn't crash on this test case. So, it
could be the case where some clang_delta's initialization code triggers
the bug. It's hard to dig into Clang's implementation to locate the
source. I will leave this bug open and check what would happen in
Clang's next release.
