Bug Description

In current git-head the toporouter struggles indefinitely even for very simple boards.
To reproduce:

1) prepare a simple schematic: Two connected resistors are enough

2) save as foo.sch

3) pcb foo.pcb

4) import schematic --> The resistors appear in the middle of the canvas

5) execute the command "toporouter()"
pcb claims a whole core indefinitely with no results whatsoever.

Hitting Ctrl+C in gdb after the lockup, and doing a backtrace, gives nested calls to swap_if_in_circle() roughly 10 000 deep. The offending line is gts/cdt.c:506.

    *** CONVERT PCB'S BASE UNITS TO NANOMETERS ***

    Convert base units to nm, change Coord from int to long,
    change LARGE_VALUE from a magic number to (LONG_MAX / 2 - 1).

could someone attach a known-to-hang .pcb for this? And instructions about which layers need to be visible during toporouting?

Marking "Low", because the Toporouter is generally considered to be redundant (and abandoned).

Hi,

I tries to reproduce this and it seems that a LMB-click on the drawingarea is required for pcb to regain focus and to get out of stasis.

Kind regards,

Bert Timmerman.
