Test case from EMAN2

Here's yet another test case that fails (on powerpc64-linux) and is fixed on
mainline with Jakub's patch.  However, we encountered this using GCC 4.6. 
Jakub, is it possible to backport your patch to FSF 4.6?

I looked at backporting the patch myself, but I'm not really sure what all that
GC magic macro stuff is doing to feel confident in backporting it myself.
