[Trilinos-Users] Compiling with GCC 4.8.0

Has anyone had luck building Trilinos with GCC 4.8.0?
I just gave it a shot on a Mac running OS X 10.7.5 and got the following error:
/Users/djlittl/Software/trilinos/trilinos-11.0.3/packages/epetra/src/Epetra_MultiVector.cpp: In member function ‘int Epetra_MultiVector::Abs(const Epetra_MultiVector&)’:
/Users/djlittl/Software/trilinos/trilinos-11.0.3/packages/epetra/src/Epetra_MultiVector.cpp:1166:63: internal compiler error: in prepare_cmp_insn, at optabs.c:4190
for (int j=0; j < myLength; j++) to[j] = std::abs(from[j]);
/Users/djlittl/Software/trilinos/trilinos-11.0.3/packages/epetra/src/Epetra_MultiVector.cpp:1166:63: internal compiler error: Abort trap: 6
g++: internal compiler error: Abort trap: 6 (program cc1plus)
The offending code in Epetra_MultiVector.cpp looks pretty straightforward, just a simple for loop.
It is preceded by
#pragma omp parallel for default(none)
But I'm assuming that by default, EPETRA_HAVE_OMP is set to false, so the omp code wouldn't have any effect.
I'm guessing my best course of action is to abandon GCC 4.8.0 in favor of 4.7.2. I have successfully built with 4.7.2 on a different machine.
