I don't know if it is the rihgt place to report this bug because i just took gcc-3.3.3 from portage directory and compiled it with needed flags so it is not a standard emerge compilation. anyway when i try to compile gcc-3.3.3 witch flags --target=avr --prefix=/usr/local/avr --disable-nls --enable-language=c it fails. gcc-3.3.1 compiles fine.

how about using dev-embedded/avr-gcc ?
This is a gcc bug, not a gentoo bug. Here is the gcc bug report: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14149 Scott =)
Was fixed upstream
