Code Sample:
struct ChunkLoc {
}

class Chunk {

        private ChunkLoc _loc;

        @property
        public ChunkLoc loc()  {
                return _loc;
        }
}

private struct FiberWaitingForChunk {
}

class WorldCache {
        FiberWaitingForChunk*[ChunkLoc] _fibersWaitingForChunks;
        void chunkLoaded(Chunk chunk) {
                _fibersWaitingForChunks.remove(chunk.loc);
        }
}

Output:
Internal error: backend/type.c 304

(Code doesn't make much sense because it's a very reduced scenario)
(Kudos to DustMite)

Any progress on this?
Still happening with dmd 2.058 on windows.

This only seems to happen when passing a struct to remove by value. If you pass it by reference everything is fine.

Reduced repro case + workaround:

struct ChunkLoc {}

ChunkLoc Get()
{
  return ChunkLoc();
}

int main(string[] args)
{
  int[ChunkLoc] aa;
  aa.remove(Get());

  //workaround
  //auto value = Get();
  //aa.remove(value);
  return 0;
}
