This glibc made it into the chroot we use to produce rawhide, which
promptly started causing invalid pointer free errors when yum was

*** glibc detected *** /usr/bin/python: free(): invalid pointer:
0x00007fffa6ead9ab ***

Granted, this was a chroot on a FC6 box, not sure if that's going to
"taint" things, but I had to roll back glibc in order to get a rawhide
compose going.
