rust-cross-canadian hasn't officially worked properly or been
supported. In assessing whether a patch is better or worse, it is
useful to know which cases regress and which improve. I had hoped this
list of failures would be smaller. I will admit I don't know whether
this is better or worse than before so I guess that is the next thing I
need to determine.

What we don't know right now is which combinations work and which don't
so we can't even tell people what is expected to work and what
isn't/doesn't :(

I mentioned this report in case someone can work out the pattern, or
even better, understand what a fix looks like...

Cheers,

Richard
