[postgis-users] Geos broken

[Gilles Bassière]

Hi,

I got no answer for the issue below. I also tried to post a message on 
the geos-devel mailing list but it seems like nobody listen to it :/
I'm still having the issue and I don't know how to track down the problem.
Does anybody can help ?

Thanks in advance
Gilles
