Compiling some packages fails when using -flto with the new gcc-4.5.0

[Piotr Juźwiak]

I am using gentoo

my emerge --info (if it helps in any way):

The failing packages are gstreamer, glib, gtk+ (that's at least 
the ones i stumbled upon, if you need me to test some more i 
can do that)


Compilling glib fails when linking (as does gstreamer):
