-----------------

It is not 100% identical to the reported message in c#1, but possibly its the
same 'warning-is-now-considered-error' problem?

There are further references here:

I can open a seperate BZ if needed.

Has the mentioned commit b68362278af94e1171f5be9d4e44988601fb0439 been released
on 13.2 yet?
