Aborted

what exactly does this mean?

edit: I tried commenting out my destructors(I'm not freeing memory elsewhere)..still gives the same error

[Nick Evan]

Probably that you're trying to free() memory that you didn't allocate (malloc)

[AutoC]

I only use new and delete and Im not freeing anywhere else except my destructors...which I commented and I still get the error...what other possibilities exist?

[Nick Evan]

You could post the code so we can have a look?

Its solved...it had to do with a declaration..thanks

Its solved...it had to do with a declaration..thanks

i have the same exact problem. what do you mean by the problem being a declaration? i have a function that returns an array. int* getNum() { return num1} and num1 is an array. and i have another integer array. int* num2. num2 = new int. num2 = ln.getNum(). (ln is an object that is irrelevant). any help would be appreciated. thanks in advance!
