--- Comment #2 from timon.gehr at gmx.ch 2012-01-24 07:38:16 PST ---
The issue is that "it compiles and runs without error". (the second assertion
asserts that there is memory corruption) The compiler has to either:

- enforce the 'scope' storage class in @safe mode by flow-analysis.
- not perform the scope delegate optimization in @safe mode.

Change the second assertion to 'assert (x == 123);' to see the error.
