2.95: nested constructors seem to cause unwarranted error in this situation.

[Christopher Baus]

I believe I have found an undocumented C++ bug that occurs under fairly
specific
conditions.

It seems calling a triply nested constructor causes an error if there
are two or more parameters passed to the outside constructor.  I have
tried to reduce the sample code as simple as possible.

I believe the test example is 100% acceptable, and (I hate to say it),
but the MS compiler seems to accept this code.

Thanks for the good work.  Requested output follows.
