Subsys: Dot
Version: dot version 1.9 (Fri Jan 31 11:51:16 EST 2003)
System: *-*-*
Severity: critical
When re-enabling the two last lines in the end of the input-file, dot crashes and dr. watson says "Exception: access violation (0xc0000005), Address: 0x004384dc"

Dot is run using the command "c:graphviz>dot -Tsvg -omm.svg"

After Dr. Watson, the command prompt re-appears, no error description from dot is visible anywhere
Input file:
[erg] A smaller graph causing the problem is Removing any edge or decrementing any weight by 1 causes the problem to go away. The core dump arises during the second network simplex to set node positions. The obvious guess is that integer overflow is occurring.
Fix: Sorry :0)
