           Summary: [hammer-3.3 regression] Infinite loop while compiling
                    kernel with VRP
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: optimization
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: gbeauchesne at mandrakesoft dot com
                CC: aj at suse dot de,gcc-bugs at gcc dot gnu dot org,jh at

  GCC host triplet: i686-pc-linux-gnu

Hi, the testcase that is about to be attached fails to complete compilation
(after 1 day :) with the following flags: -mpreferred-stack-boundary=2 -Os
-fno-strict-aliasing -fno-common -fomit-frame-pointer -falign-functions=4. VRP
seems to be the culprit as compiling with only -O -fvrp also fails.

This bug is only available on GNU C version 3.3.1-hammer 20030703. This is a
regression since 3.3-hammer 2003/05/13 which didn't have VRP actually.
