Summary and Info:
pacman -S haskell-uuid fails with a segfault in a clean staging chroot. The relevant haskell rebuild is currently stuck here.

Steps to Reproduce:
1. create a clean staging chroot: staging-x86_64-build
2. arch-chroot into the root chroot, or a copy of it
3. run: pacman -S haskell-uuid

Output with --debug:
