Import graph dependent lambda code generation bug is mostly fixed in 2.064 (eg.
bug 10857). And with 2.064, the OP code (main.d + test.d + -version=bug) does
not cause any runtime problem. So the issue seems to be fixed already.

> - issue 5064 (???): program crashes when using map and delegate
> - issue 7978 : map, take and iota functions with delegates

All of listed issues are fixed right now.
