5527 – Bug in http://www.digitalmars.com/d/2.0/ctod.html#closures ?

Dear Community,
Applying "dmd" (version 2.051 for Linux) to a source file xxx.d with the content of the example "Dynamic Closures", with "followed by "void main () { ; }", I get the following error messages (where n = number of the line "c.apply (comp_max)" in it):
xxx.d(n): Error: function xxx.func.comp_max (int i) is not collable using argument types ()
xxx.d(n): Error: expected 1 function arguments, not 0
xxx.d(n): Error: function xxx.Collection.apply (void delegate(int) fp) is not collable using argument types (void)
xxx.d(n): Error: cannot implicitly convert (comp_max()) of type void to void delegate(int)
Anybody got an idea, of what could be wrong?
With kind regards,
Christian

Dear Community,
forgot to explicitly remark, that my question was put with regard to the >first< example, not to the one with function literals (although from the context with the definition of the line number, that should be obvious).
Regards, Christian
