[Libmesh-users] "internal compiler error"?

[David K. <dkn...@se...>]

Has anyone seen this error before?

   CXX src/error_estimation/libmesh_devel_la-exact_error_estimator.lo
/home/dknez/software/libmesh-src/src/error_estimation/adjoint_refinement_estimator.C:434:1: 
internal compiler error: Segmentation fault
Please submit a full bug report,

The bug is not reproducible, so it is likely a hardware or OS problem.

I'm using gcc-4.6.3 on Ubuntu 12.04. I got the above error with "make 
-j8", and for some reason I don't see it when I just do "make". This 
issue certainly seems unrelated to libMesh, but I just wanted to ping 
the list about it...
