Hi Paul,

I did enable debugging in my postgres: *./configure
--prefix=/usr/local/pgsql2/ CFLAGS="-g -O0" --enable-debug *

The only issue the debugger does not step into anything defined inside
(postgis/gserialized_gist_2d.c
or postgis/gserialized_gist_nd.c) but it steps into other locations. What
do you think?

Here's an example:

*SELECT ST_Intersects(ST_GeographyFromText('SRID=4326;LINESTRING(-43.23456
72.4567,-43.23456 72.4568)'),
ST_GeographyFromText('SRID=4326;POINT(-43.23456 72.4567772)'))*

I placed a breakpoint inside *postgres* in:

*/src/backend/executor/execQual.c* inside function:
*ExecMakeFunctionResultNoSets* in Line:

*result = FunctionCallInvoke(fcinfo);* // as you already know, this is the
postgres macro which invokes functions as the ones defined inside postgis
The debugger nicely stepped into *postgis/geography_inout.c* function:
*geography_from_text* but NOT *gserialized_overlaps* defined inside
*postgis/**gserialized_overlaps_nd*


Thanks,
Ruby
