// The situation is that we are capturing a
|
||
|
|
// () value by ref. We generally feel free,
|
||
|
|
// however, to substitute NULL pointers and
|
||
|
|
// undefined values for values of () type, and
|
||
|
|
// so this caused a segfault when we copied into
|
||
|
|
// the closure.
|
||
|
|
//
|
||
|
|
// The fix is just to not emit any actual loads
|
||
|
|
// or stores for copies of () type (which is of
|
||
|
|
// course preferable, as the value itself is
|
||
|
|
// irrelevant).
