I have a class with an integer pointer, which I have not initialized to NULL in the constructor. For example:

class myclass
{
private:
char * name;
int *site;
}

myclass:: myclass(....)
: name(NULL)
{
.....
}

other member function “delete [] “ the variable before initializing it.

Ex:
void myclass:: copy_site ( int **Values, int *from)
{
int *old;

old = *values.

Delete [] old; <<<<<ß here I am getting SEGV
...............
..............
}

But I am getting SEGV at “delete []”.

Surprisingly it is not happening every time. For only some inputs it is certainly working fine.

What could be the reason?
If it is because of initialization, why is working for some inputs and certainly not for other inputs?

I have observed with workshop that, for some inputs it is automatically getting initialized to NULL, and for other inputs it is certainly not NULL (dangling pointer).

Thanks in advance,
