OK, so I tracked down what's going on with the Mac builds, looks like we're
tripping over an icky GCC 4.0 optimization bug which is "optimizing out" the
NULL pointer checks in LLPipeline::compare_pools, probably inadvertently
triggered by the changes for SNOW-643 (Water flickers and disappears in
patches).
More info and a temporary work-around at SNOW-761
I'd appreciate it if someone more familiar with the work from SNOW-643 could
take a look at what may be causing it and a better solution.
Aimee.
