at line 732 of distella.c:

                for (charcnt=0;charcnt<15-strlen(nextline);charcnt++)
                    printf(" ");

If strlen(nextline) is >15 at the beginning of this loop, the loop counter
will overflow... printing lots and lots of spaces (MAXINT plus or minus a
few)... On a DOS machine, this is just annoying (you get 65530-something
spaces), but on a Linux machine (or I suppose on a Win32 machine with a
32-bit compiler), it's devastating, since it prints something like 4 billion

The only time strlen(maxline) > 15 though, is when disassembling code that
has invalid .NOOP opcodes (x4 and xC). Dunno how common this is, but it
definitely happens when disassembling Super Breakout. On my win98 machine,
I get 65562-byte lines in the output... on my Linux machine, I would get
`disk full' if I sat and waited long enough :)

The easy fix is change the 15 to a 16 and recompile.

Now I have to figure out why it crashes instead of displaying the help, if
you call distella with no arguments (doesn't do that in DOS...)
