--- Comment #1 from Iain Buclaw <ibuc...@gdcproject.org> ---
Distilling the code down to C++.
---
struct DArray
{
size_t length;
int* ptr;
};
void foo35(DArray)
{
static int x[5];
foo35({5, (int*)&x});
}
---
And equivalent D (that ICE's on AArch).
---
struct DArray
{
size_t length;
int* ptr;
};
void foo35(DArray)
{
static int x[5];
foo35(DArray(5, cast(int*)&x));
}
---
On notable difference between the two is that where gdc generates the following
call:
foo35 ({.length=5, .ptr=(int *) &x});
In g++, the CONSTRUCTOR is wrapped into a TARGET_EXPR. This is at least one
thing that could be done differently, applying that to all CONSTRUCTORs passed
via parameters.
I was thinking that we already do some sort of special case for CONSTRUCTORs,
but no, it's only empty aggregates.

The proposed fix would be applied after here.
