I've recently investigated similar problem w.r.t. performance of std.regex on particular use-case/pattern. In fact it dig up an interesting bug with inlining in the compiler along the way.
It took about 5 minutes to test that enum used instead of static devastates performance but quite some time to figure out the actual "infection chain". And indeed suspicious collections/d_array_literal is what I've seen in what supposed to be GC-free loop (callgrind is awesome).
