Comment(by andymorf):

 After interminable investigations it seems to me that this in a problem of
 the JVM using the MSVCR100.dll runtime and my new MapGuide and Geos-Dll
 are compiled with vc12-platform toolset (VS2013) - before switching the
 whole dev-env from vc10 to vc12 things worked ok.
 I even switched function MgGeosUtil::Intersection to the recommended and
 thread-safe version of the geos-c api (with *_r ending) and the crashes
 remained.

 Debugging sessions allways resulted in access violations when freeing
 objects, mainly of type std::XYZ...

 IMHO this rises a big question mark concerning reliability of the Mg-Java-
 API being compiled with VS2012/13 (as long as the JVM stays at 2010
 runtime)!
