Bug 1294 – referencing fields in static arrays of structs passed as arguments generates invalid code

import std.stdio; struct TestStruct { int dummy0; int dummy1; int dummy2; } void func(TestStruct[2] testarg) { writefln(&testarg); // outputs m's address, correct writefln(&testarg[0]); // outputs m's address (same as above), correct writefln(&testarg[0].dummy0); // outputs m's address (same as above), correct writefln(&testarg[0].dummy1); // outputs the contents of the stack, one DWORD higher than the "testarg" argument (which holds the address to m) - the saved stack pointer? writefln(&testarg[0].dummy2); // outputs the contents of the stack, two DWORDs higher than the "testarg" argument - the return address } TestStruct m[2]; void main() { writefln(&m); // for reference func(m); } This goes back from at least 1.001 and up to 1.017 and 2.000. It works on GDC.

Fixed DMD 1.018 and DMD 2.002
