Is #684840 a gcc bug?

[Tobias Hansen <tobias.han@gmx.de>]

Hi,

I'm not sure what to do about this bug. bsnes 0.088-3 FTBFS with certain 
gcc versions:

gcc-4.7.0-12 FTBFS
gcc-4.7.1-1  works
gcc-4.7.1-2 FTBFS
gcc-4.7.1-6  works

Judging from the gcc changelog, this could be related to the fix for PR 
c++/53137,
which was applied in 4.7.0-12 and 4.7.1-2, but not in 4.7.1-1.

Since it works with the newest gcc packages, it might be a bug in gcc 
rather than in bsnes.

Could you tell me if this is a gcc bug and if so, what I should do to 
get a fix into Wheezy?
If it is a gcc bug, is it RC because it causes a RC bug in another package?

Best regards,
Tobias Hansen
