The application through segmentation fault when it calls prepForComplete. I have checked same test script on sst-master and sst-13 released version both branch throughs segmentation fault in prepareForComplete in sst-core.

Please let me know if anyone have seen similar issue and any workaround for this. Thank you in advance.
