http://d.puremagic.com/issues/show_bug.cgi?id=3559 Summary: DMD 1.048+ fails to take function pointer from overloaded member functions Product: D Version: 1.051 Platform: All OS/Version: All Status: NEW Severity: regression Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: klickverbot gmail.com The following code compiles and works fine on DMD 1.047 and older (DMD 1.023 was the earliest one I tested), but no longer compiles with DMD 1.048 up to DMD 1.052 because the compiler cannot »choose« the correct overload when it tries to create the delegate/function pointer. In older versions, the casts were enough of a hint. Note, however, that the code compiles without any errors if the overload I try to get the address of is the last one declared – in the example below, getting the address of »void foo( float a )« would work fine. --- template addressOf( alias fn, Type ) { const addressOf = cast( Type )&fn; } class A { void foo( float a ) {} void foo( int a ) {} void bar() { void* dg = addressOf!( foo, void function( float ) ); auto blah = cast( void delegate( float ) )&foo; if ( cast( void* )blah.funcptr == dg ) { // Stdout( "not overridden" ).newline; } else { // Stdout( "overridden" ).newline; } } } class B : A { override void foo( float a ) {} override void foo( int a ) {} } void main() { A a = new A(); a.bar; A b = new B(); b.bar; } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=3559This is because bug 52 was fixed. The compiler used to accept all kinds of garbage.If I am not misunderstanding you and the snippet I posted is in fact invalid code (it looks very strange indeed, but this is the only working version I and the folks at #d could come up with), there are now two seperate issues: Firstly, this bug should in fact be an »accepts-invalid« one, since it compiles if you put the function declarations in a certain order (see the original report). Secondly, there really ought to be a way to get this check to work for *both* overloaded and non-overloaded functions – or neither of them. With my language designer as well as my developer hat on, the restriction to non-overloaded functions is a rather annoying shortcoming… -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
