Number: 158 Title: Nodes disappear with ports Submitter: Emden R. Gansner Date: Tue Jun 18 16:35:44 2002 Subsys: Dot Version: 1.8.6 System: *-*- Severity: minor Problem:
In the graph below, setting headport causes the tail node to disappear.
Setting tailport removes the head node. Setting both is even weirder.
Input:
digraph G {
abc -> def [headport=":nw", tailport=":sw"];
}
Fix:
Chars were used for small negative numbers in poly_port in shapes.c,
but if chars are unsigned, -1 becomes 255. Changed to use explicit
signed chars.
