internal compilation error

[vbgl]

The following program should be rejected with a nice error message (which one?); it currently crashes.

inline fn aux(reg u8 x) -> inline int {
  inline int r;
  if x == 0 { r = 0; }
  return r;
}

export fn main() -> reg u8 {
  inline int t;
  reg u8 f;
  t = aux(0);
  f = t;
  return f;
}
