Usually this means the program had deleted some object twice
or applied the pointer to non-existen object somehow.
For example the statement "f= 0;" was missed in your program
or there is not protection "if (f) " calling f->Method as the fourth line
presents:
1. TObject *f;
2. delete f;
3. f = 0;
4. if (f) f->Method();
I suspect you should check your TShowerEvent::Clear() method first.
