[cfe-dev] Finding all instances of calls to a specific function using ASTMatcher

The only thing I can suggest is to use clang-query and start from the most
basic matcher, say functionDecl, then gradually constrain it using hasName,
etc. See at what point you get the crash. Reducing your input source might
also help, if this is a Clang bug you'll have a minimal repro case. I've
only tried my query on a super simple file.
