           Summary: root/array.d leaks
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: minor
          Priority: P1
         Component: dmd

With -version=GC root/array.d will leak memory.
But only when dim is 1.

This is because it is putting it into smallarray, instead of allocating memory.

It can be verified by setting SMALLARRAYCAP to 0 and removing the if statement
in the destructor.

During my testing with dmd as a library it will result in ~0.5mb leakage. The
test cases were small, but in much larger cases this could be quite serious for
reusability.

This could be a by product of other issues, I do not know.
