It would appear that the /RTC1 compiler flag (equivalent to /RTCsu) is
causing this run-time assertion failure:

What's strange is that I only get this failure when I build with the
'NMake Makefiles' generator.  If I generate with 'Visual Studio 8 2005'
instead, then open 'numeric.sln' in the IDE and build
numeric-placement_new from there, it runs fine.

I poked around in the BuildLog.htm files (for VS2005) and build.make
files (NMake) and convinced myself that CMake builds that use the NMake
generator are specifying /RTC1, while VS 2005 builds are not.

That number appears to be 1500. `:-}  I re-checked this and discovered
that the test does eventually time out after 25 minutes.
