I've been working on a libc implementation for WebAssembly.
This source file triggers the bug.

The static function _right is so bulky that it compiles to a
standalone function, but it's exported as an extern function,
which probably causes name clashes.

No minimal example was conceived due to difficulties to write
a bulky enough function.
