>Description:

In <URL: http://gcc.gnu.org/ml/gcc-bugs/1998-12/msg00022.html > it was
reported that format attributes didn't work on methods.  The example
given now works, but it isn't documented that argument numbers must be
increased in this case to allow for a hidden argument 1 (as discussed
in that message).

>How-To-Repeat:

See example in the indicated message.

>Fix:

Someone who knows C++ (so not me) should add documentation to the
description of format attributes in extend.texi discussing their use
on C++ methods.
