[mkgmap-dev] Assert error

Hi Gerd, this seems to have gone away again. It may be that my PC was
getting hot and producing spurious errors.

Cheers,
Mike

Hi Mike,

this seems to be a limit in the img format. If I got that right an entry in
NET refers to more than 0x80 entries in RGN.
This seems to be too much and should not happen. The program should probably
split the road somewhere
so that more entries in NET are created or it is split too often. The
question is where to detect the situation.
Maybe you can post a patch or describe how to reproduce the problem?

Gerd

Hi, I have just started getting an assert of "too many polylines at level 1"
with my latest UK build. Any suggestions what I need to change?

  java.lang.AssertionError: too many polylines at level 1
