This is a problem with binding overloaded functions. See
<http://www.boost.org/doc/libs/1_54_0/libs/bind/bind.html#err_overloaded>
I typically static_cast, when I can't use a C++11 lambda.

Nate, as far as I can see this isn't an issue with binding to an overloaded function (because the function isn't overloaded!), it's selecting the correct constructor overload based on the return value of boost::bind.

Putting a temporary TestBind::t_ProcessFunctionInt in between the creation of the TestBind object and the bind to Test::process works; it's the implicit conversion between the return value of boost::bind and the two constructor overloads which is failing.

ie: this works:

TestBind::t_ProcessFunctionInt fn = boost::bind((&Test::process), &t1, _1);

TestBind f(fn);

this doesn't:

TestBind g(boost::bind((&Test::process), &t1, _1));

In other words, it's the choice between

TestBind(t_ProcessFunctionInt) {}

TestBind(t_ProcessFunctionShort) {}

which fails

Note that making the constructors explicit doesn't work:

explicit TestBind(t_ProcessFunctionInt) {}

explicit TestBind(t_ProcessFunctionShort) {}
