SgExpression *arrayRefs()

I am running Sage++1.7 and discovered thajt this fuction never returns.
I think the fix is in low_level.c line 5356
You need to add:

return list

just like the routine: SgExpression *symbRefs() 
which is located a few lines lower down.

I havent tried this fix yet so if I'm wrong let me know
