That's just the GDAL API.  We still use the GEOS C++ API.

I don't think the GDAL issue is a ABI problem.  The ABI shouldn't change
if you compile with or without optimization.  And should also only be a
problem when you mix binaries produced by different compiler (versions).

I suspect that this is a more general GCC 4.3 optimization problem -
IIRC Debian also currently compiles mapserver w/o optimization on GCC
4.3, because of that.

BTW did you verify that on platforms other than amd64?
