          Hardware: All

When I try to recompile a betterC application (developed under 2.095.0), I get
the following NEW error. I do not use expceptions. 

dmd  -I/home/larry/Github/escheme-dbc/src -c

       instantiated from here: `emplaceRef!(Vector!(void function()),
Vector!(void function()), int)`

I do not use exceptions anywhere in this application. The application compiles
find under 2.965.0.  I pressume the aforementioned package DID star using
exceptions and now is invalid for betterC use.
