Years ago someone tracked down a layout test failure to optimizations
on a particular file in WebKit.
  http://code.google.com/p/chromium/issues/detail?id=8475
"The extra precision is causing a problem in:
third_party/WebKit/WebCore/platform/graphics/Color.cpp
which can be "fixed" by compiling with -ffloat-store.  "

However, that was long enough ago the error may no longer exist in that file.
