I've been looking for the source of the memory leak. I was able to
reproduce "the problem" on my Linux machine.
I couldnt find any reason for a leak. I had orginally thought that the
POSTGIS->GEOS or GEOS->POSTGIS converters might be leaking.
My first check was on the POSTGIS->GEOS converter.
I've attached a simple little .cpp program that creates polygons the
same way as the postgis code does. I checked with valgrind, and it
leaks a constant amount of memory (probably static structures inside
So, that indicates its not the POSTGIS->GEOS convertor. I also looked
at the postgis geomUnion() functions. I dont think there's a leak there.
I'm looking at the GEOS->POSTGIS converter and I think I might have
found a problem.
ps. how do you pronounce "strk"? stUrk? stIrk?
