Obj-C compiler error

I ran into an Obj-C compiler error.  The problems seem to be with
optimization as running with the optimization level < O2 is a work
around to the problem.

/gcc version:
------------
Reading specs from
/usr/local/gnu/packages/gcc-2.95.2/lib/gcc-lib/powerpc-unknown-linux-gnu/2.95.2/specs

system type:
------------

Please submit a full bug report.
See <URL:http://www.gnu.org/software/gcc/faq.html#bugreport> for
instructions.

Preprocessed output:
--------------------
I couldn't send the preprocessed output (NSSplitView.mi) because the
file was too large and your mailer rejected it.  Is there another way
to send the file?

Thanks,
