If you look up a bit further in the logs you'll find things like:

******************** TEST (llc) 'kernel01' FAILED! ********************
Execution Context Diff:
Compared: 1.143052e+02 and 1.000876e+02
abs. diff = 1.421754e+01 rel.diff = 1.420509e-01
Out of tolerance: rel/abs: 1.000000e-04/0.000000e+00

which seem relevant. Perhaps some info before that too.
