--- Comment #10 from Jack Howarth <howarth at nitro dot med.uc.edu> 2012-10-06 00:47:13 UTC ---
I can confirm on 10.7.5 that the provided test case fails with the gcc47-4.7.2
package from current MacPorts but compiles fine with my gcc47-4.7.2 packaging
from fink.
MacPorts's g++-fsf-4.7 fails the link as...
% /opt/local/bin/g++-mp-4.7 -std=c++11 testcase.cpp
