I don't think this ever got filed upstream and the 4.5 branch is now closed. We'll have to wait for 4.6 to go stable.

I can confirm this bug continues with opencv-2.4.3 and gcc-4.5.4, but does not exist with gcc-4.6.3 . Is there anything we can put in the opencv ebuild to prevent building with the older compiler? It would be nice to prevent this kind of error, because the error message is pretty difficult to find and parse in the output.
I have that bug, too. gcc-config is switched to: x86_64-pc-linux-gnu-4.5.4 # emerge -pvt media-libs/opencv [ebuild U ] media-libs/opencv-2.4.3 [2.3.1a-r1] USE="gstreamer gtk jpeg opengl png threads%*

*** Bug 471342 has been marked as a duplicate of this bug. ***
I was having the same problem when 'x86_64-pc-linux-gnu-4.5.4' was set as my default compiler. For a work-around, I followed the instructions at http://www.gentoo.org/doc/en/gcc-upgrading.xml to change my default compiler from 'x86_64-pc-linux-gnu-4.5.4' to 'x86_64-pc-linux-gnu-4.6.3', and then have been able to 'emerge opencv' successfully.
This bug still exists. It applies to ebuilds in the stable tree. Can we please update the opencv-2.4.5 ebuild to add a build dependency for gcc 4.6.3 or higher? 4.6.3 seems to be the minimum stable gcc that is required to successfully compile.
4.6/4.7 are stable now so it shouldn't be a problem. CCing maintainer in case they feel differently. Note that if you do decide to require >=4.6 it needs to be done by checking the compiler version in pkg_pretend/setup rather than adding a build dependency.
gcc-4.9 is stable now, so throwing away older bugs we don't plan on doing backports for as this should be fixed w/4.9+. please re-open if it's still an issue with 4.9.3+ though.
