Use of open in signal declaration causes crash #1057
Description
Hopefully I found what is causing the error that I mentioned in #1045. Passing open to an already constrained portion of a type declaration causes NVC to crash. Replacing open with 7 downto 0 (or any other range, causes the test to pass).

sigA(0)(0) <= '0';
