--- Comment #11 from Sam James <sam at gentoo dot org> --- (In reply to Andrew Pinski from comment #10) > Someone would have hit this a long time ago, in GCC 4.3.0 or latter. My point was that some software has recently started building with PCH by default and hence it's only appeared now and I was surprised at the number of people who were affected. I understand the bug isn't new, it's just been exposed by a change in the ecosystem.
