Segmentation fault using operator delete in C ++

I'm trying to make a program work in c++. When I create an instance of a class and take the reference to it, everything is fine:

PolyCRTBuilder test1(parms);
PolyCRTBuilder *p = &test1;

But when I use dynamic allocation to create the instance, it gives me a segmentation fault error as I try to free the memory:

PolyCRTBuilder *test2 = new PolyCRTBuilder(parms);
cout << "test2 variable created" << endl;
delete [] test2;
cout << "test2 variable deleted" << endl;

This last code returns me

test2 variable created

Segmentation fault

Why is this?

Solution

  • delete [] test2; deletes an array, but you create a normal object. Try delete test2; instead.

    You should also familiarize youself with smart pointers, for example unique_ptr and shared_ptr. Raw pointers are bad style in modern C++ and makes you program error prone.
