Thanks!  My Linux build is inside a virtual machine so the memory limitation of the virtual machine would explain the difference between Linux and OS X.  I’m now doing a a serial build and monitoring the memory usage via the “top” command.  I see cc1plus going as high as 35% of the memory.  If all four threads tried to access that much memory at once, that could exhaust the memory. Possibly something in the build process requires more memory now than it used to require.
