Another problem with my nested classes: I expected this program to print "Hello" but it throws a "Error: Access Violation" instead. The only way around this seems to be to redeclare Bar,bar and the constructor in Foo2... What's wrong?

# module nestedclass2;
#
# private import std.stdio;
#
# class Foo
# {
#     class Bar
#     {
#         void doSayHello()
#         {
#             sayHello();
#         }
#     }
#     Bar bar;
#
#     void sayHello()
#     {
#         writefln("Hello");
#     }
#
#     this()
#     {
#         bar = new Bar();
#     }
# }
#
# class Foo2 : Foo
# {
# }
#
# int main(char[][] argv)
# {
#     Foo2 foo = new Foo2();
#     foo.bar.doSayHello();
#
#     return 0;
# }

This seems to me, like a bug, which will be fixed in the next dmd version. Please try to add a default ctor to Foo2. Perhaps this helps.

Tried it, it didn't help.

What compiler and platform? It works for me (DMD 0.156, Linux).

It worked for me, too, with DMD 0.157 under Windows.

However, compiled with -inline, it throws an Access Violation.

Oh right, it was DMD 0.157 under Windows, an i was using "inline" too.
I'll file a bug report.
