Can someone help me find issue in move semantic? I am getting issue , but could not find what is causing failure.

Answer 1

you don't seem to check that counter is not a null pointer before dereferencing it ( line 97 ).

Answer 2

Thanks. I thought it was due to double delete and not focused on this aspect.

Correction done. Thanks again
