A short while ago, I sent out a shell archive file for a top processes
display program called "top". Since then, a bug has been discovered that,
in certain cases, causes "top" to segmentation fault. Here is a shell
file that changes "top" to fix this bug, upgrading it from version 1.4 to
version 1.5. Thanks to Prentiss Riddle at ut-sally for pointing this
problem out to me.
Extract the shell file at the end of this message and place it in the same
directory that contains the "top" distribution sent earlier. Then, run
the shell file with your favorite shell. It will automatically apply the
changes to the appropriate files (in this case, "Changes" and "top.c"), so
make sure that you have the original versions of these files in that
directory. Once you have done this, remake "top" with "make".
