Hi,

I faced the same problem.

In the score-src/SCore/mttl-ult/ult/mpcxx_defs.h file, you will the  
following line

----
/** use Sys-V user context for high portability but low performance
**/
#define ULT_USE_USER_CONTEXT
---

and uncomment the line. Then it will not use the JB_SP not JB_PC.  
Next, change the  score-src/SCore/build/config/score file.

As in the above, "-DSCORE_NO_CHECKPOINT" should be added to the  
config params. This disables the checkpoint/restart.

All the above problems are fixed in the upcoming SCore 6.0 which will  
be release next month.
