Summary

0000063: LinearMemoryInteractionGraph causes uninformative crashes in ScoreFunction::operator() when used with symmetry

Description

http://www.rosettacommons.org/content/fix-back-bone-design-fixbb#comment-4933 [^]

Apparently, -linmem_ig breaks symmetric packing. PDInteractionGraph works, LinearMemoryInteractionGraph does not.

I think the bug is that OnTheFlyInteractionGraph (parent of LinearMemoryInteractionGraph) clones an incoming scorefunction incorrectly:

OnTheFlyInteractionGraph.cc:465 score_function_ = new scoring::ScoreFunction( sfxn );

instead of, say,

score_function_ = sfxn.clone();

which would preserve SymmetricScoreFunction's subclassedness.

Additional Information

I am testing if my suggested code change passes the tests, and have requested that the reporting user test against his use case.

Notes
(0000051) smlewis (Administrator) 2012-08-08 10:08	This is not exactly fixed - the change to the ScoreFunction type was unintended and incorrect, which has been fixed in 50279. LinearMemoryInteractionGraph is still not compatible with symmetry, but that is explicitly stated in code exposed by r50279, so I'm refiling that as a feature request instead.
