The bug is probably somewhere else. Make sure the proper language options
are set up before parsing the source file, and that you're printing out any
diagnostics. My guess would be that the source is failing to compile (wrong
options, or can't find some standard header, or something), and the
diagnostics are being discarded, and clang is replacing the parameter type
with 'int' in error recovery.
