It seems to trigger edge > splitting once on the 2 to 4 edge: Hmmmm... maybe it was one of my local patches? I'll try to figure out what went wrong later tonight. I added logic to be clever about edge types... when splitting an edge, the type should remain except a forward edge becomes a cross edge. (You can do it out on paper...) Perhaps that upset things? It doesn't seem like codegen is using those terms in the usual MST meanings :(</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
