Tested with DMD 2.081.2. This bug does not seem to occur on DMD 2.073. The following example causes DMD to ICE with a segfault: $ cat example.d class Foo { shared this() { } } void main() { scope foo = new shared Foo(); } $ dmd example.d Segmentation fault If you replace scope by auto then it will compile just fine.

This looks like a backend bug.
