This is indeed a texinfo bug.  I have

  @macro Example
  @example
  @group  
  @end macro

  @macro endExample
  @end group
  @end example
  @end macro  

  @Example
  groff -a -man -Tdvi troff.man | less
  @endExample

and this now fails.

Nothing in the documentation prevents this -- it only talks about
incompletely nested macro definitions -- and up to 4.6 it has worked
flawlessly.

I strongly suggest to use groff.texinfo as a torture test for texinfo
(both the makeinfo and TeX part), as it has repeatedly shown bugs and
problems in texinfo.  Had I known the release date of 4.7 in advance,
I would have been able to test it.

There are other problems also which I will try to investigate soon.
