This glibc made it into the chroot we use to produce rawhide, which promptly started causing invalid pointer free errors when yum was called: *** 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. -- Jesse Keating Fedora -- Freedom² is a feature!
