[mkgmap-dev] Mapsource crashes while calculating a routeFrom GerdP gpetermann_muenchen at hotmail.com on Sun Jan 19 06:39:15 GMT 2014
Hi Andrzej, thanks for reporting. I can reproduce the problem and I see that the display tool claims that there is an error: ERROR: Last point of a joined line without node-flag This error message doesn't show up for the img file created with r2795. In opposite to r2795, the later versions do not split the road with > 250 points in StyledConverter, but later. It seems that the write routine in LinePreparer still needs corrections for this case, it already contains a comment. /* * Current thought is that the node indicator is set when * the point is a node. There's a separate first extra bit * that always appears to be false. The last points' extra bit * is set if the point is a node and *this is not the last* * *polyline making up the road*. * *Todo: special case the last bit* */ @Steve: Did you learn something new regarding this extra bit? If not, I will revert the changes to the line splitting algo. Gerd popej wrote > Hi, > > I have observed crashes for some time. Mapsource 6.16.3 indicates a bug > in module MPL_MAP.CPP.
