Spatialite assert when using intersection filter
Fabian Schindler
I'm running into the following assert within spatialite when using the
intersection filter:
python: geos_ts_c.cpp:2605: int
GEOSCoordSeq_setOrdinate_r(GEOSContextHandle_HS*,
geos::geom::CoordinateSequence*, unsigned int, unsigned int, double):
Assertion `0 != cs' failed.
The application terminates (no exception or the like). With other
backends (tested with PostGIS), there is no such error.
I'm using the filter like this:
qs = MyModel.objects.filter(
footprint__intersects=poly
)
My gdb stacktrace (I could not find any debug symbols for spatialite,
and was not able to build them on my own):
#0 0x00007ffff69efba5 in raise (sig=<value optimized out>) at ../

... (only Python calls here)
Which is kinda strange, since I could not find a call to
`GEOSCoordSeq_setOrdinate_r` in the `gaiaToGeos` function.
Any help is appreciated :)
Thanks,
Fabian
