struct Foo { void bar() { } void delegate() dg = &Foo.init.bar; } # dmd test.d Stack overflow

This is a recursive definition, I guess this should be expected. Lowering to minor issue.

Compier stackoverflows and segfaults are NOT minor issue.

Changed importance to 'major'.

More simple case: struct Foo { int dg = &Foo.init; } In AddrExp, compiler will try to convert Foo.init to lvalue with Expression::toLvalue, but it is not possible, then try to output an error message like "Foo(...) is not an lvalue". But, the initializer of the field dg contains Foo.init itself. So it will occurs *recursive printing*. Foo(Foo.init) -> Foo(Foo(Foo.init)) -> Foo(Foo(Foo(Foo.init))) ...
