Merge pull request #1654 from RosettaCommons/roccomoretti/fix_gcc47_segfault
Fix GCC segfault issue.
Older versions (4.7.2, 4.8.1) of GCC have internal compiler errors (the compiler segfaults)
with code in SemiRotamericSingleResidueDunbrackLibrary.tmpl.hh. Separating out the variable initialization over two lines 'fixes' the issue and allows Rosetta to be compiled.
