--- Comment #20 from Markus Trippelsdorf <octoploid at yandex dot com> ---
I've tested this further on my Gentoo box and it turned out
the many nontrivial packages that I've compiled failed
with "trap invalid opcode". From a QOI perspective this is a 
nightmare. Not every user of the compiler is a developer, e.g.
as a Gentoo user I don't care deeply about most ebuilds, I just
want them to compile without fuss. And for this I need a compiler
that is as permissive as possible.
