           Summary: internal compiler error: in record_reference, at
                    cgraphbuild.c:60
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: swestrup@gmail.com


The code that triggered this bug is almost certainly in error, but as its
caused an internal compiler error, it seemed worth reporting. That said, I
don't really know *what* caused the bug, except to say that it happened when I
declared my four matrix variables in the attached code (M a ... M d) to be
static.

The code is one unit test from an ongoing project, and I've provided the plain
.cpp code (for reference) and a pre-processed file so you have a chance to
reproduce the bug.

In case it matters, here are my system specs:
