           Summary: [3.3.2 regression] 2GB mem not enough for sucessful
                    compile
           Product: gcc
           Version: 3.3.2
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: debian-gcc at lists dot debian dot org
                CC: gcc-bugs at gcc dot gnu dot org

This is a regression from 3.3 CVS from 20031005, at least on i486-linux. The
file attached compiles almost instantly with the CVS version, but just eats
memory with the released version.
