Summary: sfcb bad memory access possible

Initial Comment:
Running sfcb under valgrind reveals invalid memory
accesses. Although there's no reproducable runtime
error resulting from this up to now, it's not unlikely
that a segmentation fault could happen under certain
circumstances.
The reasons:
- there's a bug in the string and array buffer
expansion logic in objectImpl.c, which can lead to
reading past of the heap
- length calculation of string segments is buggy and
can lead to reading past the string buffers
