------- Comment #2 from paolo dot carlini at oracle dot com  2010-05-13 19:10 -------
Seems pretty obvious to me that this is *not* a libstdc++ issue. I'm
tentatively categorizing it as middle-end and adding Honza due to Comment #2.

Yes, we need the help of people running darwin, on x86_64-linux (-m64) too the

looks like it is 159354. 
159353 is OK and the logs for the other changes look unrelated.

this is still present, AFAICT, for *-*-darwin* at r162047.

Honza, since it was your patch that triggered this, any ideas on what we could
do to debug/solve this one?

in particular this; "error: Inline clone with address taken " is still
happening.

On x86_64-apple-darwin10, these failures at -m32 and -m64 appear to be
suppressed when building with --enable-checking=release and reappear when
building with --enable-checking=yes.
