Thanks for looking into this.  The bug is however a bit earlier. The
propagation
stage should never put anything into lattices of aliases (we probably should
add
checking assert that those are never used) and instead of that always go across
the alias into the final symbol.

I guess somewhere there is missing call to ultimate_alias_target (or
function_symbol)
