--- Comment #11 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Lauri Kasanen from comment #10) > The gcc docs state that any version of gcc above 3.4 is supported, so this > is still a bug. They say to start with an existing GCC binary, not that *any* version will work. If a particular version is buggy then you might not be able to use it, so use a different version.
