seg fault -> bug report via e-mail about raftlib

[jonathan-beard]

So the issue boils down to the way shared pointers are copied, this fixes the issue...but without calling the constructor each time for the FIFO element it'll segfault. The relevant section of the C++ memory header file is attached via screen shot below. Interestingly running this inside a debugger magically fixes the issues.

#include
#include
#include

int
main( int argc, char **argv )
{
std::shared_ptr< std::uint32_t > x = std::make_shared< std::uint32_t >();
*x = 100;

char data = (char) malloc( sizeof( char ) * sizeof( x ) );
#ifdef REPLICATE
auto test( reinterpret_cast< std::shared_ptr< std::uint32_t > >( data ) );
#else //FIX
auto test( new ( data ) std::shared_ptr< std::uint32_t >() );
#endif
/* should segfault **/
*test = x;
std::cout << x.use_count() << "\n";
std::cout << test->use_count() << "\n";
return( EXIT_SUCCESS );
}

Solution to this bug is to use a template function specialization with std::enable_if for object types so that non POD will have the default in-place constructor called to initialize any data members that could potentially be needed....but that's just a first take something far simpler should fix this......
