------- Comment #1 from jojelino at gmail dot com  2010-01-08 17:50 -------
here is vtable dump for klass
as you can see , klass->engine of dynamic version is NULL 
whereas static version got proper instance though....
so klass->engine->verify(klass); invokes SEGV.......
but why does it happened??? some linker problem??
$ diff static dynamic -ud
