Details:

Hi all, i don't know if this is a GCC problem or a octave problem, actually
with the octave dev version i can't compile it, i get the same errors for all
gcc versions i test:

libinterp/octave-value/ov-bool.cc:320:1: error: same_comdat_group list across
different groups
libinterp/octave-value/ov-bool.cc:320:1: internal compiler error:

I use gentoo 64, and i try compile with 5.4, 5.4-dev and 6.4 versions of GCC.

I try differents configurations for the installation but sadly the same
result.

Thx.
