infinite loop

[strk]

I got qgis 1.7.0 enter an infinite loop in main gui. Attached gdb and saw it being in pal::LabelPosition::getCost(), pretty much every time I did break it.

I know, this bug report sucks... sorry about that. Next time I'll try to debug more.

Oh, here's some more, in the screen buffer:

[wonder]

Could you please post a sample shapefile that exhibits this behavior?

Isn't that a polygon layer with very complex shapes? (that might take a long time, but not infinite).

Eh, not easy to reproduce. I was checking postgis tables, very simple shapes from example topologies. It could be the data disappeared during the run ... Doesn't seem to depend on dataset as on second run it worked fine.
