Yes, my case is very similar to the one described by Kiko Piris, and
I also think this is getting off topic.

I tried the bisect with the same compiler and then for other tests
I recompiled from scratch each time on a tmpfs to make sure I was not
messing things up. On this machine, ccache is not used.

So I am suspecting a recent glibc or binutils upgrade (gcc downgrade did
not solve the problem) and even if some people noticed problems with, my issue seems different and only distro-related.
