More demos crashing for LC build than x86

[jamesETsmith]

General

I'm seeing three demos crash for LC builds that don't crash for x86. See the details below for a breakdown. This is almost certainly related to #4.

Details

# results.log from x86
             bc_demo number of errors: 0
            bfs_demo number of errors: 0
             cc_demo number of errors: 1
    gappagerank_demo number of errors: 0
        mtx2bin_demo number of errors: 0
            ss2_demo number of errors: 1
           sssp_demo number of errors: 0
             tc_demo number of errors: 0

Circled back to check this again and it looks like we're matching between x86 and LC now (I checked with 2 nodes in the simulator).
