Question

In GDB I get:

 
(gdb) backtrace
0  0xb7d91544 in strcpy () from /lib/libc.so.6
1  0x08048982 in ISBN::ISBN(char const*, ISBNPrefix&) ()
2  0x08048d4a in main ()
(gdb)

From this code:

ISBN::ISBN(const char* str, ISBNPrefix& list) {
    if(isValid(str)) {
            isSet = true;
            sprintf(*isbnStr,"%s",str);
    }
}

What exactly would be causing this?

isbnStr is created in the header:

class ISBN
{
 ...
    char* isbnStr[11];
 ...

Any ideas on what I could be doing here to cause this seg fault?

The call in main is:

ISBN* isbn = new ISBN("7999999008",*prefix);

Answer 1

isbnStr is an array of strings (or more specifically character pointers), not an array of characters. I think you meant to do char isbnStr[11];
