Please submit a full bug report.

I bootstrapped with the following compiler:

Reading specs from
/usr/lib/gcc-lib/armv4l-unknown-linux-gnu/2.95.1/specs
gcc version 2.95.1 19990816 (release)

I have tried applying modified versions of the patches we build the
above 2.95.1 compiler with and the same result occurs.  The above
problem is based on a version checked out ~5PM EST Oct 8/99.
