Auto-generated clang script
The attached auto-generated code takes infinitely long with optimization level
2 (-O2). When switching to -O1, it works fine.
Using clang on ArchLinux:
clang version 3.7.1 (tags/RELEASE_371/final)
Target: x86_64-unknown-linux-gnu
Thread model: posix
Maybe that's already fixed in upstream, and somebody could quickly test that
with the attached scripts/source file.</pre>
