#9511: Non-static data member
 Reporter: Bjorn Reese <breese@…> | Owner: burbelgruff
     Type: Bugs | Status: new
Milestone: To Be Determined | Component: typeof
  Version: Boost 1.54.0 | Severity: Problem
 Keywords: |
 Consider the following example:

   void foo(int value) {}
   struct alpha {
     int value;
     typedef BOOST_TYPEOF(foo(value)) return_type;

 This example compiles just fine with g++, but with clang++ it only
 works if compiled with -std=c++11, otherwise it gives the error
 message below. I believe that clang is correct (this diagnostics was
 [https://llvm.org/viewvc/llvm-project?view=revision&revision=154073 added]
 in clang 3.1.)

 Is this a bug in Boost.Typeof or is it expected behavior? Is there a
 workaround for it?

 The error message is:

 /home/breese/src/treediff/treediff/main.cpp:17:30: error: invalid use of
 non-static data member 'value'
     typedef BOOST_TYPEOF(foo(value)) return_type;
 /usr/local/include/boost/typeof/native.hpp:41:76: note: expanded from
 #define BOOST_TYPEOF(expr)

 1 error generated.
