unitarize_link_test has a memory leak #94

Closed maddyscientist closed 10 years ago

maddyscientist commented 11 years ago

unitarize_link_test has a memory leak, as indicated below. Justin, can you see if you can find this?

Punting this to 0.5.1, since it is a relatively harmless leak as a result of using static pointers. This will be fixed naturally as Guochun's code is objectified.

I dragged my heels on this. It would be straightforward to fix, but not high on my list of priorities. Once the domain decomposition is done, I'll look at it.
