--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-07-14 14:49:53 UTC --- (In reply to comment #0) > After emerging sys-devel/gcc-4.4.5 on Gentoo Linux kernel-2.6.38-gentoo-r6 What does this mean? Not everyone uses gentoo or wants to understand its pkg system. I assume you're building gcc-4.4.5 with a newer gcc? > Completed installing gcc-4.4.5 into > /var/tmp/portage/sys-devel/gcc-4.4.5/image/ > > ecompressdir: bzip2 -9 /usr/share/gcc-data/i686-pc-linux-gnu/4.4.5/man > ecompressdir: bzip2 -9 /usr/share/gcc-data/i686-pc-linux-gnu/4.4.5/info > > * QA Notice: Package has poor programming practices which may compile > * fine but exhibit random runtime failures. > * > > /var/tmp/portage/sys-devel/gcc-4.4.5/work/gcc-4.4.5/libgcc/../gcc/unwind-dw2-fde.c:321: > > > warning: dereferencing type-punned pointer will break strict-aliasing rules > * That code has already changed to avoid those warnings: http://gcc.gnu.org/viewcvs?view=revision&revision=147705 So I think this is FIXED
