I can't reproduce it on any of my machines -- the above is from adding
'strace -f' to the specfile, and trying a scratch build.
I suspect it's either 64KiB pages, or something trying to use Altivec
when it shouldn't. Probably the latter, given the nature of the problem.
Will try to reproduce on the POWER5, although I think one of the routers
between me and it is dead so I can't reach it at the moment.
