ARC bombs after archiving a zero-length file; it tries to print the percentage compression, calculated of course as: compressed-size/original-size or something like that. The result is a floating exception. The patch below fixes it. *** arcpack.c~ Mon Jul 18 14:38:27 1988 --- arcpack.c Mon Jul 18 14:39:45 1988 *************** *** 155,161 /* standard cleanups common to all methods */ if (note) ! printf("done.

Go ahead and install this fix, it's simple enough and the problem does arise often enough to need it. Keep your original distribution handy, though, because a lot of diffs are on the way.
