Hi,
When trying to use a cross-ar from vanilla binutils-2.16 or
binutils-2.16.1 on FC4, I am observing this
(Here as part of bootstrapping gcc):
# arm-rtems4.7-ar rc ./libgcc.a libgcc/./_udivsi3.o
*** buffer overflow detected ***: arm-rtems4.7-ar terminated

I there a fix/work-around? Is it a binutils or FC problem?
I hardly can believe nobody has been facing this issue before, but
haven't tried to investigate in depth, yet.
