--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
And the original expansion bug simply says we're not getting function nesting
/unnesting correct.

The D.2371 local (what the SAVE_EXPR resolves to in the outer function) needs
to be pulled from the static chain but I do not see any.  In fact the
middle-end isn't presented with nested functions at all but it looks like the
C++ FE
does lambdas in its own way but forgets about cross-"function/lambda"

I'm out-of-the way for that C++ FE issue.  Maybe it doesn't want to share
the SAVE_EXPRs in the end.  Who knows.
