Confirmed. Seems to be a regression in 4.6.
At first glance your code looks completely innocent. I think the bug may be
somehow related to the interface and the result variable having the same name.
Removing (or renaming) the result variable makes the error go away.
In any case the problem seems to occur during module writing. Backtrace:
