Error in running Finalizer #18

Closed yeesian closed 9 years ago

yeesian commented 9 years ago

Running test/test.jl gets me

$ julia test/test.jl
Loaded SCIP version: 3.1
done

I can reproduce it with test/mpb.jl:

Still getting this with the new code generation, so it doesn't seem to be a problem there:
