Hi Mark, and thanks for your quick response.
Should I track down the earliest buggy revision, or is the r1337:1343 range of revisions specific enough?
One more observation: r1338 is fine. Between r1338 and r1343, the only changes according to svn:log are to message reporting and MAX_ARC_LENGTH.
Could you please try reducing the value of MAX_ARC_LENGTH (in StyledConverter.java), initially right back to 25Km as that's what it's been for a long time and see if it makes any difference for you. If that doesn't help, you could try using smaller values for some of the other constants there.
Guess what, this works: Index: src/uk/me/parabola/mkgmap/osmstyle/StyledConverter.java =================================================================== --- src/uk/me/parabola/mkgmap/osmstyle/StyledConverter.java (revision 1365) +++ src/uk/me/parabola/mkgmap/osmstyle/StyledConverter.java (working copy) @@ -84,7 +84,7 @@ public class StyledConverter implements private final Map<Way, Way> originalWay = new HashMap<Way, Way>(); // limit arc lengths to what can be handled by RouteArc - private final int MAX_ARC_LENGTH = 75000; + private final int MAX_ARC_LENGTH = 25000; private final int MAX_POINTS_IN_WAY = LineSplitterFilter.MAX_POINTS_IN_LINE; Best regards, Marko
