*** Bug 582904 has been marked as a duplicate of this bug. ***
Virtual table verification might not be supported on powerpc architecture. On later version (gcc-5.1) vtv flag seems to have been disabled. http://git.freesa.org/toolchain/gcc/blob/master/libvtv/configure.tgt I have checked that this package compiles with USE="-vtv"
I can confirm this is also a problem on the MSP430 architecture for gcc 4.9.3. It doesn't compile by default, it does after I add -vtv to my msp430 gcc line in my use file.
fixed here: https://gitweb.gentoo.org/proj/crossdev.git/commit/?id=be2e2afe53400c7339cc2d105fdfb114c55da74d
Unfortunately, on mingw64 target gcc stage 2 also fails to build unless -vtv is added to GUSE_DISABLE_STAGE_2. This is true both for gcc-4.9.3 and gcc-5.3.0 - current stable and unstable gcc, respectively.
