Hi Andrzej, the same problem occured with maxlon=0 in r4065. The new code works fine as long as you don't try to retrieve data outside the initial area. I've added some unit tests to prove that now, see http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4068 Gerd ________________________________________ Von: mkgmap-dev <mkgmap-dev-bounces@lists.mkgmap.org.uk> im Auftrag von Andrzej Popowski <popej@poczta.onet.pl> Gesendet: Dienstag, 16.

A tile with lower edge at 0 compiles properly, but don't you expect the same problem with lower or right border? -- Best regards, Andrzej _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
