I'm trying to get an app working called pi-address. It is QT based and is
used to muck with the address database of a palm pilot. It seems to work
well except for the import/export ability. It gets a SIGSEGV and my C++
isn't quite up to schnuff.

If you guys have some patience, the relevant info might be more meaningful
to you than it is to me. (I really want this thing to work.):

BTW, I have qt-1.40 installed under RH-5.1.

When I tell pi-address to export the database to a csv file, then I get
the SIGSEGV. I ran it inside gdb and got a stacktrace.

Here's the stack:

(gdb) bt

The line of code that it's dying on is this:

                  s->sprintf("\"%s\",\"%s\"\n",
                             (a->getNote())     ? a->getNote()     : "", 
                             (a->getPrivate())  ? "1"              : "0");

Since the sprintf (#4) is on the stack, I assume that that means that
getNote and  getPrivate have already run. They are *not* inlines. The
instanciation of s is:
  QString s;


The class definition for a is:
class AddressRecord : public QObject
{
    Q_OBJECT

public:
    AddressRecord();
    AddressRecord(const Address *, int iCat=0, bool bMod=FALSE);
    ~AddressRecord();
    
    void putShowPhone(int);
    void putFN      (const char *);
    void putGN      (const char *);
    void putTitle   (const char *);
    void putCompany (const char *);
    void putPhone1  (const char*);
    void putPhone2  (const char *);
    void putPhone3  (const char *);
    void putPhone4  (const char *);
    void putPhone5  (const char *);
    void putAddress (const char *);
    void putZIP     (const char *);
    void putTown    (const char *);
    void putState   (const char *);
    void putCountry (const char *);
    void putDefined1(const char *);
    void putDefined2(const char *);
    void putDefined3(const char *);
    void putDefined4(const char *);
    void putNote    (const char *);
    void putPrivate (bool);
    void putModified(bool);
    void setCat     (int);
    void putPhoneLabelIdx0(int);
    void putPhoneLabelIdx1(int);
    void putPhoneLabelIdx2(int);
    void putPhoneLabelIdx3(int);
    void putPhoneLabelIdx4(int);
    
    int         getShowPhone();
    const char *getFN      ();
    const char *getGN      ();
    const char *getTitle   ();
    const char *getCompany ();
    const char *getPhone1  ();
    const char *getPhone2  ();
    const char *getPhone3  ();
    const char *getPhone4  ();
    const char *getPhone5  ();
    const char *getAddress ();
    const char *getZIP     ();
    const char *getTown    ();
    const char *getState   ();
    const char *getCountry ();
    const char *getDefined1();
    const char *getDefined2();
    const char *getDefined3();
    const char *getDefined4();
    const char *getNote    ();
    bool        getPrivate ();
    bool        getModified();
    int         getCat();
    int         getPhoneLabelIdx0();
    int         getPhoneLabelIdx1();
    int         getPhoneLabelIdx2();
    int         getPhoneLabelIdx3();
    int         getPhoneLabelIdx4();
    
private:
    Address Addr;
    bool    bPrivate;
    int     iCat;
    bool    bModified;
};

Is there anything obvious going on here? Many thanks in advance.
