Yes, that method wasn't doing the correct thing for intersection DOFs...
I applied a fix in r2064. The only relevant test I could find (test-composed-iis-gfs)
compiles, but crashes during ALUGrid creation on my machinem so I can't verify
whether the LocalFunctionSpace is now working, as I don't even get that far...
Could you please test whether the patch fixes the problem on your end?

Thanks,

Steffen
