I did not notice this one, the attached patch "cures"
the problem on my x86_64 box using 3.4.1 to bootstrap
(at the total cost of 10-15 seconds of rebuilding various things).

I'm not sure if I'm just working around -O2 code generation
problems in 3.4.1 or doing something more "correct"
with respect to the bootstrap process.

Arnaud?

I'll do more testing shortly (x86_64 starting with 3.3 and x86 with 3.3
and 3.4).

as author of the patch that introduced the problem has an idea?
