Summary0000066: Win32 dot, crashes on some input
Description



Win2000 machine.



The following input crashes dot, the command line is:
<CD>
dot -Tpng KPLSupermanDump.txt -o temp2.png -v
</CD>



if cluster3 is removed, and its nodes merged into the main graph g,
then it works.



and the '-v' output gives:
<CD>
