--- Comment #5 from Maxime Boissonneault <maxime.boissonneault at calculquebec dot ca> --- Any pointer on what could be wrong ? Maybe a clue is that we compiled GCC not with the system GCC, but with another GCC ? Basically, we started with the system GCC. We compiled GCC, GMP, MPFR, MPC_V, with that system GCC. Then, we uninstalled the system GCC and its libstdc++ and recompiled those with the GCC we had just compiled. >From then on, we just used that GCC to compile the next one (we started with 4.8.0, then 4.8.2).
