I just tried this with a 2.95.1 cross compiler targeting mips-dec-ultrix4.4 and
could not reproduce the failure.

Probably the best thing for you to do is

  1. Make sure you can reproduce the bug with gcc-2.95.1

     <objdir>/gcc/cc1 -O chillstdio.i

  2. Assuming it fails #1, then my guess would be that gcc has mis-compiled
     itself.  To test that theory, compile chillstdio.i with the stage1
     compiler.

     <objdir>/gcc/stage1/cc1 -O chillstdio.i


What direction we go next will depend on the outcome of those two tests.
