Probably the message is not too explanatory because of the pretty printer
but what it means is that (QUOTE (UNSIGNED-BYTE 8)) is not a valid type
specifier, as you already found out.

As for the reason why this is only seen once on every session is because ECL
now caches some functions, such as the type comparisons. One of them is used
in the type propagation and type checking code and the cache is preserved
among compilation sessions. I should fix this.
