I'm trying to update my CentOS 5.6 boxes to 5.7, and on every single one
of them yum is failing with a segmentation fault: the error happens when
yum is checking the 'base' repository.
[root at picard yum]# yum update

Running yum under strace produces lots of output, the last lines are:

It seems that the primary.xml.gz file is somehow corrupted, but I've
already tried a "yum clean all" and a "rm -rf /var/cache/yum/*" without
success.
Apart from being at CentOS 5.6 and all having this problem, the boxes
have very few in common:
- 2 physical machine running 5.6 32-bit, one in my office, the other in
a datacenter
- 1 physical machine running 5.6 64-bit in another datacenter
- 2 KVM VPS running 5.6 32-bit in a third datacenter
- 1 Xen VPS running 5.6 64-bit in a fourth datacenter
There was a thread on the forum some months ago which mentioned this
same problem, but the original poster didn't find a solution (or if he
did, he didn't share it with the forum). Any suggestion is appreciated,
I cannot reinstall those boxes with 6.0 for at least 4/5 months.
