9291	can not compile sink->set_filter(phoenix::bind(&my_filter, ...	Johan Lundberg <lundberj@…>	Andrey Semashev	"The line 

     sink->set_filter(phoenix::bind(&my_filter, severity, tag_attr))

from the documentation, here: http://www.boost.org/doc/libs/1_54_0/libs/log/doc/html/log/tutorial/advanced_filtering.html fails to compile. 

*How to reproduce*

Find this tutorial (linked from the doc above):

      http://www.boost.org/doc/libs/1_54_0/libs/log/example/doc/tutorial_filtering.cpp

Then change '#if 0' to '#if 1' to activate that part of the tutorial and comment out the
other definition of init(). I get errors related to phoenix bind on line 155:

    sink->set_filter(phoenix::bind(&my_filter, severity, tag_attr)); 

I can't judge if this is a problem with boost log itself or the documentation/tutorial.

I used boost 1.54 and tried gcc 4.7.2 and 4.8.1, and tried both c++11 and c++98 mode with the same result.

          
* Details on the compilation error: I think this is the relevant
part of the error message:
