           Summary: gcc do not respect stack argument list order
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: critical
          Priority: P1
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org

  GCC host triplet: i686-

It seems like gcc do not respect reverse argument order on stack.
The program attached produces different code (therefore output) with different
optimization levels. This seriously brokes ABI. I got same results for gcc 3.2
and 3.3.1-release compillers on ia32 and sparc platforms. Try cc with -O0, -Os,
-O3. For my understanding the only right stack content produced with -O3 option.
