sametail

Is there a limit for sametail definitions number in DOT ?

Hi,
could someone find out why the following example produces an error with dot, whereas it works fine when removing the last line (or replace T6 with T5, for example)?
digraph "test" {
Node0 -> Node1 [sametail=T1];
Node0 -> Node1 [sametail=T2];
Node0 -> Node1 [sametail=T3];
Node0 -> Node1 [sametail=T4];
Node0 -> Node1 [sametail=T5];
Node0 -> Node1 [sametail=T6];
}
Thank you !

Limit for sametail/samehead definitions number in DOT ?

Hi,

I tried to draw hierarchical graphs with dot, involving a limited number of nodes (about 30), but with more than 100 edges and, especially, many edges having to start from same points. So I used "sametail" attribute, but got an error at generation.
Looking for the reason of the failure, I noticed that I got the error if more than 14 "sametail" and/or "samehead" attributes are defined in the dot file I am defining (it works fine with 13 "sametail" definitions, but not over).
