I think this is a bug of iota() (or a problem in core.memory.GC.malloc):


import std.range: iota;
import std.array: array;
void main() {
    auto a = array(iota(1L));
}



DMD gives:

...\std\array.d(243): Error: function core.memory.GC.malloc (uint sz, uint ba =
cast(uint)0) is not callable using argument types (ulong,BlkAttr)
...\std\array.d(243): Error: cannot implicitly convert expression (_param_0 *
8LU) of type ulong to uint
...\std\array.d(231): Error: cannot implicitly convert expression (_param_0) of
type ulong to uint
...\std\array.d(194): Error: template instance

It compiles just fine with the latest master. I believe that that iota was taking a size_t before, which then didn't work with long on 32-bit systems. It was fixed in

https://github.com/D-Programming-Language/phobos/commit/d08f0e6621e1ceb1d8a4cded975507f775c8857e

I think that there was a bugzilla entry that went with it, but it's not in the changelog, so I don't know what it was.

I have just compiled the latest DMD, druntime and Phobos, and I see some errors still. Maybe it's my fault, I don't know.

This still doesn't compile on 2.059 Win32
