Well the problem is that DMD doesn't perform no checks whatsoever 
when you do selective imports. So yes, I think both bugs are 
related.
However, I re-opened 18234 as we want to include the test case to 
the testsuite gets fixed.

BTW it's a shame that https://github.com/dlang/dmd/pull/6676 
which will be pulled soon while being very close to the bugs in 
question, doesn't fix either of them.
