Ptrdist/ft Execution Bug

[lenary]

There's a bug and ptrdist/ft is failing at execution time.

It's not in our list of our original 10 benchmarks for the preliminary evaluation, but we should get it checked and working. Not going to investigate it tonight, probably tomorrow afternoon.

The execution bug only happens with our large inputs.... since we've gone back to regular sized inputs, I'm not sure whether I should be concerned.

I'm still going to update ft to be entirely checked (PR pending)
