Summary0001671: dot hangs on some input with tailport&headport&same rank

The following input (a reduction of an example of dot
syntax on wikipedia) causes dot to hang indefinitely (or... at least
for 3 or 4 minutes now, which is effectively forever!) on my dual-core
machine. By removing any element from the sample input, dot will
process the file in less than a second.
Steps To Reproduce

digraph g {
    A1 -> B1
    A2 -> B2
    A3 -> B3
    A2 -> A3
    B1 -> B3 [label="xyz" tailport=s headport=s]
    B2 -> B3
    { rank=same; B1 B2 B3 } }

Additional Information

[erg] The base problem is that the spline router produces an incorrect
route, which goes wildly outside the given boxes.
The code recognizes something has gone wrong. This is usually a case
where increased sampling helps but since a line segment is involved,
finer sampling doesn't help.
