Re: Problem with C++ method pointers

[Artak Avetyan]

Many bugs are here. Follow notes - "^^^".
First change the code, then retry.  Not sure that this is g++ compiler error.

Regards,
Artak.

 ^^^^^^^^^^^^^^
1) Incorrect init., use:  Jug jug[] = {{(Macro::io_init), "howdy", "dude!"}}
2) don't think good idea to use Macro::io_init - non static funtion, better
  Macro mac;
Jug jug[] = {{(mac.io_init), "howdy", "dude!"}}

^^^^^^^^^^^^^^^^^
incorrect call, right code is
(mac.*(jug[0].fp))(fp);
