Hi!

What does new int[0]?

In QString (about line 10300) is:

    QChar* result = 0;
    uint l = 0;
    if ( str ) {
        if ( maxlen != (uint)-1 ) {
            while (str[l] && l < maxlen)
                l++;
        } else {
            // Faster?
            l = strlen(str);
        }
->        QChar *uc = new QChar[l];
        result = uc;
        uint i = l;
        while ( i-- )
            *uc++ = *str++;
    }                               

if str == "", then the marked line will
do new QChar[0]. But what does it return?
A test said me, it returns something, but
what does it return? Is it defined? I must
admit, it's the first time I think about this
"problem" :)

Greetings, Stephan
