DMD 2.112.0 fails to compile an array variable initialization with an array literal and a UDA

[programandala-net]

After upgrading DMD from v2.111.0 to v2.112.0 (on Debian 13.2, x86_64) I have found an issue, which I have isolated in the following code snippet:

void main()
{
	enum var = true;
	@var string[] list = ["A", "B", "C"];
}

v2.111.0 compiles the code as expected but v2.112.0 halts with the following message:

Internal Error: array literal ["A", "B", "C"] (...) should have been lowered to a _d_arrayliteralTX template

Removing the var UDA fixes the problem.

The lowering shares the same internal pass as @nogc, revealing the root cause dates back to at least 2.070:

void main() @nogc
{
       string[] b = ["A", "B", "C"]; // @nogc error, correct behavior
    @1 string[] a = ["A", "B", "C"]; // no error, incorrect behavior
}

@dkorpel, thank you for fixing it.
