           Summary: Regression: Optimizer produces incorrect code for ARM
                    target
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: pgonzalez at bluel dot com
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-pc-cygwin
  GCC host triplet: i686-pc-cygwin
GCC target triplet: arm-arm-elf

The attached file compiles correctly with GCC versions 3.0.4 and 3.2.3; 
however, incorrect output is produced with GCC 3.3 and the mainline 
snapshot "gcc-3.4-20030730".

The problem goes away when optimizations are disabled.  This problem does not 
occur on other targets, e.g. i686.
