Abort error on 64-bit Linux running mandel.py

[teoliphant]

When running examples/mandel.py on 64-bit Linux.

python: /home/ilan/aroot/work/llvm-3.1.src/include/llvm/CodeGen/LiveInterval.h:130: llvm::LiveRange::LiveRange(llvm::SlotIndex, llvm::SlotIndex, llvm::VNInfo*): As
sertion `S < E && "Cannot create empty or backwards range"' failed.
Stack dump:
0. Running pass 'Greedy Register Allocator' on function '@__numba_wrapper___numba_specialized_create_fractal_double_double_double_double_uint8_5B__3A__2C___3A
__3A_1_5D__int'

This is on Wakari whose /etc/issue is:

CentOS release 6.3 (Final)
Kernel \r on an \m

The Python is 64-bit.

This is the same error Andy saw on Unix on TACC machines.

Note that @sklam committed a test for this in 33e2323.

This is fixed by using a newer gcc compiler.
