option_description::option_description(3 args) is exception-unsafe

[anonymous]

Given the code in libs/program_options/src/options_description.cpp:

option_description::
option_description(const char* name,
                   const value_semantic* s,
                   const char* description)
: m_description(description), m_value_semantic(s)
{
    this->set_name(name);
}

s leaks in case if initialization of m_description throws.

The simplest cure is to make option::description::m_value_semantic member to be before all other members.

The proper solution is to use smart pointers everywhere.
