--- Comment #4 from Dlang Bot <[email protected]> --- @FeepingCreature created dlang/dmd pull request #15354 "Fix issue 24018: set length manually via runtime function." fixing this issue: - Fix issue 24018: make `array.length = n` `@system` if default construction is disabled on the array type. This is needed as there is otherwise no good way to resize an array of non-constructable elements in user code at all. - Fix issue 24018: instead of calling `array.length =`, call the runtime function that implements `array.length =` instead. This skips the check for the element type being constructable, which is correct because concatenation doesn't expose unconstructed memory anyway. https://github.com/dlang/dmd/pull/15354 --
