[Comment 2 João P. Teixeira 2016-05-21 18:19:44 UTC]

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"

[Comment 3 Alex Orange 2016-05-24 01:40:23 UTC]

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.

[Comment 5 Maciej S. Szmigiero 2016-06-03 20:30:03 UTC]

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.
