It is often a good rule in programming to look at the first error only 
and ignore the rest.

In this case the first error shows the problem, and *after* that the 
error path after the correct diagnostics results in an internal error.

Rare error paths are often buggy since they are not usually exercised.

The internal error is surely a (minor) bug in the linker,
but it doesn't invalidate anything that happened earlier.
