The bug reporting guidelines request that you don't upload an archive of files.
The contained source file is:

#include <list>
#include <memory>
#include <sstream>

struct stmt_base;

template <typename _RawType>
struct sptr
    : public std::unique_ptr<_RawType>
{
    typedef std::unique_ptr<_RawType> base_type;
    typedef typename base_type::pointer pointer;
    typedef typename base_type::deleter_type deleter_type;
    sptr() = default;
};

struct block
{
    std::list<sptr<stmt_base const>> _stmts;
};

struct stmt_base {};

struct branch
    : public stmt_base
{
    branch(sptr<stmt_base const> c);
    sptr<stmt_base const> const alternative;
};

I can't reproduce the crash on x86_64-linux
