"&xy" used to be illegal (just use "xy",) but was recently legalized with
ANSI C.  Perhaps Manx hasn't quite finished ANSI'sizing its compiler yet?

                      ^^
                      Notice what you did here compared with above.

Yup, you're right.  There's a bug in the compiler.  Perhaps the compiler
wanted to report a warning (e.g., "& before array ignored") and the
internal error occurs when the compiler tries to report it!
