Have there been any problems with Wine on GCC 4.7?

[Scott Ritchie]

Wine is the last remaining package still depending on GCC 4.5 in the
current Ubuntu alpha, it would be nice to drop GCC 4.5 and forward port
Wine, however 4.6 is known to not work too well.

But now we have 4.7 -- have there been any bugs attributed to its usage?

Thanks,
Scott Ritchie
