Ok, I have a little more info... It is getting stuck at
agg/include/agg_path_length.h:36. This line:
unsigned cmd;
vs.rewind(path_id);
*** while(!is_stop(cmd = vs.vertex(&x2, &y2)))
{
if(is_vertex(cmd))
Returns the same coordinates over and over. vs is defined as:
(mapnik::coord_transform2<mapnik::CoordTransform,mapnik::geometry<mapnik::vertex<double,
2> > > &) @0xbfb21d58: {t_ = @0xbfb222b0,
geom_ = @0x9d98328, prj_trans_ = @0xbfb22148}
Note that it's a *vertex* that it's trying to calculate the length of.
So the bug appears to be in include/mapnik/geometry.hpp:125
unsigned vertex(double* x, double* y) const
{
*x = pt_.x;
*y = pt_.y;
return SEG_LINETO; <-- This should be zero to indicate end-of-shape
}
I'm going to try compiling this and see if it helps...
Have a nice day,
