[eigen] Infinite loop in gebp

[Sameer Agarwal <sameeragarwal@xxxxxxxxxx>]

Hi Guys,

I am using eigen 3.1.2 on a mac and  I am observing an infinite loop in

Eigen::internal::gebp_kernel<double, double, long, 4, 4, false, false>::operator() 

This is with g++4.1.2 -O3 -DNDEBUG  -fast -msse3

the same code works just fine with clang 4.0.0 

I can provide instructions for reproducing this (its corrector_test.cc of the Ceres Solver code base).

But before I do that, is there anything know about this compiler/Eigen/OS combination?

Thank you,

Sameer
