           Summary: backend/cod1.c 1677, related to structs with
                    constructors (?)
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: regression
          Priority: P2
         Component: DMD
        AssignedTo: nobody@puremagic.com
        ReportedBy: code@klickverbot.at

The following test case was reduced from code passing a core.time.Duration using std.concurrency:
---
struct Foo {
    this(long) {}
}

struct FooContainer {
    Foo value;
}

auto get() {
    union Buf { FooContainer result; }
    Buf buf = {};
    return buf.result;
}

void writerThread() {
    auto a = get();
}
---

DMD 3bfac139 (on OS X) fails with: Internal error: backend/cod1.c 1677


In the original much larger test case, the error was different, although probably related (I'll re-test it once this version has been addressed):
---

Reduced test case. Bug8283 can be either a struct or a union.
---------------------------
struct Ctor8283 {
    this(int n) {}
}

struct Bug8283 {
    Ctor8283 value;
}

Bug8283 get8283() {
    Bug8283 buf;
    return buf;
}

void outer8283() {
    Bug8283 x = get8283();
}
