I don't know whether this belongs right here or has been reported yet but
rdiff (part of RCS) dumps core when compiled on suns running revision
3.0 of Sun's software do memory allocation problems.  I believe we have
release 3 of RCS. Everything ran fine under Sun's revision 1.2 but when
we upgraded to 3.0 rdiff dumped core.  The following fix to the file diff.c
seemed to fix things.
