---------------
$  dmd main.d
Internal error: ../ztc/cod3.c 2651

This error seems to arise whenever the struct has more than one "field" (either
as real variable field or even as array), but interestingly it works for char.
'f' has to be a parameter, it compiles fine when declared as a global or local
var.
