9606	Boost.LocalFunction cannot bind pointer variables by reference on gcc/clang	e4lam@…	Lorenzo Caminiti	"Boost.LocalFunction cannot bind pointer variables by reference on gcc or clang. I have tested this against the latest boost code available in version 1.55.0 and r86799. I have tested that it works on Visual Studio though but not on gcc 4.1 (Linux), 4.6 (Linux), nor clang 5.0 (OSX). Here's the test

{{{
// Example compile: g++ -I /usr/local/include/boost_1_55_0 -o bug bug.cpp
#include <boost/local_function.hpp>
#include <stdio.h>
int main()
{
	int x = 1;
	int *px = &x;

	void BOOST_LOCAL_FUNCTION(bind& px, bind& x)
	{
		printf(""INSIDE:  &px = %p, &x = %p\n"", &px, &x);
	}
	BOOST_LOCAL_FUNCTION_NAME(fubar)

	printf(""OUTSIDE: &px = %p, &x = %p\n"", &px, &x);
	fubar();

	return 0;
}
}}}
 
The pointer values output by this program should be identical for both the INSIDE and OUTSIDE cases. Notice that value  for &px differs.

I found some ways to sort of make this work but none of them are acceptable workarounds for me:
- Binding pointer variables works perfectly in Boost.ScopeExit for all compilers/platforms that I tested
- Adding ""-std=c++0x"" to the compiler line also fixes the problem
