Hi,
This smells like a serialization bug in the runtime. Are you using
the Java (Managed) backend or C++ (Native) backend? If it is possible to
extract a smaller version of the program that exhibits the crash (or if you
can send me the larger program directly (gro...@us.ibm.com)) we can try to
take a look and diagnose.
