import std.array: array;
import std.range: repeat;
auto r = [1].repeat(1).array;
void main() {}



DMD 2.065alpha gives me:

...\dmd2\src\phobos\std\array.d(45): Error: returning a pointer to a local
stack variable
...\dmd2\src\phobos\std\array.d(49):        called from here:
trustedGetAddr(result[i])
...\dmd2\src\phobos\std\array.d(49):        called from here:
emplace(trustedGetAddr(result[i]), e)
test.d(3):        called from here: array(repeat([1], 1u))
