Just found the link to it:
http://cvs.sourceforge.net/viewcvs.py/boost-sandbox/boost-sandbox/libs/polic
y_ptr/test/
I downloaded both the test code, and the policy_ptr code, and the policy_ptr
code does not compile.
I tried compiling it on VC++ 7.1 and GNU 3.x, and both fail to compile the
code.
Boost\Policy_ptr\Policy\no_copy.hpp
The above header gives a compile error for the following line:
#include "../always_false.hpp" //(Line 12)
Boost\Policy_ptr\Policy\ref_counted.hpp
The above header gives the following error:
Boost\Policy_ptr\Policy\ref_counted.hpp(155) : error C2061: syntax error :
identifier 'U'
Line 155 has the following:
BOOST_SP_DECLARE_TEMPLATE_FRIEND(U, ref_counted_, 2)
I also notice the following:
// In Boost\Policy_ptr\Policy\ref_linked.hpp Line 20
ref_node(void)
: prev_(this), next_(this) { }
I would think the above code would result in undefined behavior, since a
pointer to an object that is not yet fully constructed is being pass to a
data member.
I'm not sure how the above code would have been tested, if it's not
compliable.
