[geos-devel] is this a big leak?

[Yury A. Bychkov]

This is weird. When I run Dave's test I don't get any leaks (at least none are
detected by my software). What are you using for memory leak detection?
Valgrind?
Can you send me the complete leak report that you get?

Yury
P.S. Oh, and can you send me your parameterized test as well?
