Arrays of Strings- stumbling over a very basic question

[anw]

I have a declaration like this (from a .h file):

class emlMsg
    {
  public:
    emlMsg(string From, int NumAddrs, string Addrs[], string To, string Sbj, string Msg)
        {init(From, NumAddrs, Addrs, To, Sbj, Msg);}

    void init(string From, int NumAddrs, string Addrs[], string To, string Sbj, string Msg);
    emlMsg& operator = (emlMsg& rhs){this->init(rhs.from, rhs.numAddrs, rhs.addrs,
                                                rhs.to, rhs.sbj, rhs.msg); return *this;}
    ~emlMsg();
    void dump(char* prefix="");
    string from;
    string* addrs;
    string to;
    string sbj;
    string msg;
    int numAddrs;
    };

(note the bolded declaration) that is initialized and has an operator = defined through the function init and has a destructor defined in a .cpp file thusly:

void emlMsg::init(string From, int NumAddrs, string Addrs[], string To, string Sbj, string Msg)
    {
    from= From;
    to= To;
    sbj= Sbj;
    msg= Msg;
    numAddrs= NumAddrs;
    addrs= new string[NumAddrs];
    for(int i= 0; i < NumAddrs; i++)addrs[i]= Addrs[i];
    dump("emlMsg::init: New Message");
    }

emlMsg::~emlMsg()
    {
    theLog.Write(LogDebug, "emlMsg::~emlMsg: deleting addrs\n");
    delete addrs;
    theLog.Write(LogDebug, "emlMsg::~emlMsg: done deleting addrs\n");
    }

(Note bolded assignment and delete statement)

Three questions:

1. When I delete addrs in ~emlMsg, I get an abort signal. Any idea what I could be doing wrong here?

2. When I declare the addrs like this:

string addrs[];

in the .h file, the compiler says:

error: incompatible types in assignment of 'std::string*' to 'std::string [0u]

What's wrong here?

3. A string assignment operator is overloaded, right, so string1=string2 actually copies from string2 to string1 instead of just assigning pointers?

I know I should be using vectors and will probably change over, but I'm really curious (not to mention frustrated) about this.

TIA,
