Thanks for your bug report. There is a known code generation bug in
the TeX area, in gcc 2.95. I'm not sure whether this is the particular
bug, or what the status of the bug is. Last I heard it was not going
to be fixed in gcc 2.95, because the bug report arrived too late for
anybody finding a proper fix in time.

OTOH, gcc 2.95 also significantly changed behaviour with respect to
programs violating the ISO C standard. If you want to experiment
further, please recompile xdvi with -fno-strict-aliasing -O2. This
option is necessary if the application is violating the ISO C aliasing
assumptions. AFAIK, at least libc might do such things in its inline
memcpy implementation (not sure about libc 5 here).

So, if you do try this, please let us know of the results.

Martin
