           Summary: ICE with 4.6.0 2010-11-26 with c++0x, in TBB's
                    <atomic> header
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jeffrey.donner@gmail.com


Created attachment 22536
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=22536
Basically the pre-processed TBB <atomic> header file as included by a .cpp

It doesn't happen without the -std=c++0x flag. 

Command line. Pre-processed, mostly-TBB-including file attached (it's the
open-source one, v3.0.3 I think.) It's renamed to .ii.cpp to satisfy the
content-type checker.
