Caliper Segmentation fault on Xeon Phi Knight landing

I annotate LULESH with caliper macros. LULESH experienced segmentation fault with the following call stack information (More details, please refer to this [caliper issue](https://github.com/LLNL/Caliper/issues/30)) :

Start with the linked Caliper issue and reproduce the annotated LULESH run on Xeon Phi Knight Landing using the provided stack trace, especially cali_pthread_create_wrapper in src/services/pthread/PthreadService.cpp. Done means determining the cause of the segmentation fault and demonstrating that the annotated run no longer crashes.
