[geos-devel] Was it a big memory leak ?

[strk]

It seems it was not, but a feature/bug of the STL library (caching).
valgrind FAQ contains tips on how to disable this binding in gcc
please read and comment on this - I think it should be specified
at configuration time wheter to force this or that behaviour
(when not possible at runtime).

--strk;

Looks like this may be Q14 in the valgrind FAQ
(http://developer.kde.org/~sewardj/docs-1.9.5/FAQ.txt).
