The problem lies in ".autoimport +", whose use is not recommended. If you
remove it, the assembler will tell you that "label" is actually undefined.
Which is true, since the symbol with this name is in scope "bar".

So what happens is that "label" is undefined, but because of ".autoimport",
the assembler will make it an import. An import has absolute addressing by
default, so the assembler assumes that the symbol is not reachable by a short

No solution (depends on your code), but I hope this clarifies things.
