Hi all,
shape-decode has been crashing on me for a certain shapefile and I can
not figure out why. I am using terragear-cs downloaded today from the
GIT repository. The rest of the toolchain runs fine.
shape-decode runs for a while and stops with the following error:
[...]
distance = 239.828
0.623843, 46.9914, 0
distance = 7.99999
0.626076, 46.9898, 0
min = -2930.42, -592.671, 200 max = 0.62615, 46.997, -200
Bucket min = -180:0, -593:2
Bucket max = 0:2, 46:7

A run under gdb yielded the following:

206 if ( b_min == b_max ) {

shape, preserve3d );
209 return;
210 }

212 SGBucket b_cur;
This happens with the following shapefile:
http://www.mguillaud.net/fg/fg_railways.tgz
Note that I can run some other shapefiles through shape-decode without
problem. That particular file was generated by PostGIS using pgsql2shp.
It does not appear to be invalid.
Any advice ?
Regards,
Maxime
