[Scip] Call to adjustedUb in SCIPvarChgUbOriginal causing solve failures

Hi all, I've recently updated the Microsoft .NET wrapper that I wrote a couple
of years ago to allow .NET Applications so that it could be used SCIP 2.0 and
Soplex 1.5. I restructured the projects to use the new Developer Studio Solution
files that were made available (thanks Wei Huang) and after fixing up a few
things that I was expecting all seems to be working as expected apart from one
problem. When I try to set an upper bound using SCIPvarChgUbOriginal() to 1e100
the new call to adjustedUb() overrides the incoming value and restricts the
upper bound to 1e20. This causes my previously working solve to now fail. I'm
not sure if it's a case that I have previously been relying on something that
was incorrect in the older versions or if this is a "real" issue with the
current SCIP version. I can supply more details on my test if it helps but at
the macro level I just wanted to first check with the the mailing list colective
wisdom as to whether the adjustedUb() interaction is kosher? Any insights out
there ?
