I can confirm that behaviour. Although in real mkgmap does not freeze (endless loop) but is working very very hard. Possibly the mkgmap code is not very optimal for the special test case.
@Steve, the code requires a very long time in the NETFile.simplifySortedRoads method because I think there are many roads with the same name. I think I remember a similar discussion some time ago? The method seems to perform a brute force method to detect connected roads with the same name. Can you have a look on it?
