This regression is caused by the fact that in 1.32, bind( &Foo::bar, _1 ) no 
longer returns a reference to Foo::bar; it wants to return by value instead.

The change was motivated by the fact that bind( &Foo::bar, bind( 
createFoo ) ), where createFoo returned a Foo by value, would return a 
reference to an object that was already destroyed.

You can fix your example by using bind<string>( &Foo::bar, _1 ), which 
should work on the compilers you listed.

The CVS version also supports

    bind<string>( &Foo::bar, _1 ) == test
