Interfaces are a particularly difficult feature to get even close to right. 
I'd expect to be finding bugs in those essentially forever (just as happens 
with finalization). Indeed, these are hard enough to implement that there 
are no plans to implement them in Janus/Ada in the forseeable future (modulo 
a customer with $$$, of course). There are a lot of other things that 
Janus/Ada needs that will take an order of magnitude less development time 
(and thus are much better choices for development effort).

This is a problem with MI in general, not just with Ada. Bugs are still 
turning up in C++ compilers, and they have more than a decade's head start 
on GNAT...
