hog-inducing C
Sorry for the unreduced testcase, but these are hard to reduce.
Attached code makes clang use at least 7 GB of RAM on an x86-64 machine at
which point my 6 GB machine is swapping so hard the compiler gets no CPU time.
[regehr@bethe tmp608]$ clang -v
clang version 3.0 (trunk 127271)
Target: x86_64-unknown-linux-gnu
Thread model: posix
[regehr@bethe tmp608]$ clang -O3 -w small.c
