           Summary: -fnew-ra gives internal compiler error: in
                    verify_wide_reg, at flow.c:549

            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: optimization

Poking around with -fnew-ra I ran across the the error message:
"internal compiler error: in verify_wide_reg, at flow.c:549"

This is with SuSE 8.1 on i386, GCC 3.3.1 (built with ./configure;make
bootstrap;make install).

I will attach the *.i file.
