[geos-devel] GEOS 3.8.0 RC3

[rmrodriguez at carto.com]

Hi,

I've run scan-build against the project and it shows ~30 issues,
some minor and some important.

I've created a PR addressing them (https://github.com/libgeos/geos/pull/238)
but there is still 12 more in case someone wants to have a look before
me (I'll try
to finish with them tomorrow).
