I tried with and without optimizations. I get garbage as expected. So, it must be
allocating a closure in spite of scope. So, it looks to me like scope is just completely ignored and does absolutely nothing at this point, unless I'm just completely missing something here.
Something must be screwed up. I dunno what, I use near-latest DMD from github and Win32 binaries. For good measure try making stack variables larger if you are on 64bit. Drop in a couple of calls to writeln before and after calling 'f' it should scramble the stack.
