Bug 18450 – ICE without line numbers on templated struct constructor call

DMD 2.078.2 on Windows. This code: struct S2(T) { T arr; } unittest { const S2!(int) b; S2!(const(int)) c = b; // Line 7 } Gives this error: foo.d(7): Error: object.Error@(0): Access Violation ---------------- 0x0065445A 0x006548FE 0x0064DBD3 0x004B0B90 0x0043FC26 0x004C794B 0x01162110 0x011623E0 With a little wiggling of the types: struct S2(T) { T arr; } unittest { const S2!(int[]) b; S2!(const(int[])) c = b; } I get an even more interesting: foo.d(7): Error: object.Error@(0): Access Violation ---------------- 0x0065445A 0x006548FE 0x0064DBD3 0x004B0B90 0x0043FC26 0x004C794B 0x773A8B88 in RtlFreeHeap 0x005797E2 0x00594C94 0x773A73F7 in RtlAllocateHeap 0x3F5011A9 0x05F6122D 0x175102F7 0x01CE5388 0x007201EF 0x01220042 0x047700C6 0x0021035A 0x05040000 0x001A0129 0x000106B4 0x00400063 0x001C00C6 0x00820021 0x00620063

Fixed in 2.078.3
