segmentation fault on private variable

[jeko]

Hi,
I'm using a class method which read and write on private variable of own
class.
During the first alghoritm cycle, method read and write correclty on
num_elts variable, but during the second cycle as soon as method wants
read (or write) the variable program is aborted and return "segmentation
fault". Why? num_elts is a long variable.

thanks

Andrea

Lots of possible reasons.
Post the smallest complete progamm that shows that error in action
and someone might be able to help.

It is possible that the pointer to the object is invalid. Check the
value of this.
