I do not understand the error traceback. It should NOT look like this. Is that really the exact output from a single failed run? There snould not be multiple messages of ----Error Message ---- etc. It shoul immediately after the first listing of Configure options show the complete stack where the problem happened instead it printed an initial error message again and then again and then finally a stack. This is not suppose to be possible. Are you running with multiple threads AND gpus? That won't work.
Anyways I cannot find anywhere a list of Cusp error messages that include the numbers 46 and 76; why are not the except messages strings ???
