New description:
sage-4.7.rc2 built on an opteron system [skynet:flavius
(x86_64-Linux-k8-fc)] with `SAGE_FAT_BINARY="yes"`, and then moved to
another x86_64-Linux system will fail with a segmentation fault on the
following code:
{{{
set_random_seed(0)
p = next_prime(randrange(2^96))
q = next_prime(randrange(2^97))
n = p * q
qsieve(n)
}}}
`qsieve` is from the flintqs-20070817 spkg, which by default builds
with `-march=opteron` on ''all'' x86_64 systems (''and'' in 32-bit mode).
