Created attachment 30386 [details, diff] crypto++-5.1-gcc34.diff
fixes the gcc 3.4 problems for me. crypto++ relies on undefined identifiers beeing resolved on template instantiation time, but this is not iso C++ conformant. so the diff is quite big. pls also consider including the amd64 patch from bug #49034. i have a changed ebuild with both patches and it runs nicely.
Thomas: Have you submitted these patches upstream?
Committed... Should be hitting the mirrors soon. I put the gcc 3.4 patch up on the distfiles mirror to keep the portage tree smaller.
