          Issue ID: 21498
           Summary: Functions with delegate parameter overloaded on
                    attributes fail miserably

The offending code is below (you should be able to comment-in  nogc using

On my Windows machine, the listing compiles and runs seemingly without errors.
Note that all attributes including  safe are circumvented. For  nogc, use

On run.dlang.org, running all DMD compilers, only 2.066 correctly points out
attribute violation. Since 2.067 the compiler is beigng "killed by signal 11"
(whatever that means). LDC segfaults.
