[postgis-devel] invalid memory alloc request size

[strk at refractions.net]

Which GEOS version ?
Does content of lwgeom/postgis_geos_version.h matches it ?
What RCS id of lwgeom/lwgeom_geos.c and lwgeom/lwgeom_geos_wrapper.cpp ?

Please uncomment the PGIS_DEBUG_CONVERTER #define in lwgeom_geos.c
to see wheter it's pgis->geos or geos->pgis failing.

--strk;
