This is the error I get when I run my program:

It compiles fine, but I'm not sure what is causing this error. I have three files, my main: program.cpp, LList.h, and LList.cpp.
Can anyone please help me?
Thanks...

This doesnt mean much to non godlike programmers.
We need some code please.
you might be trying to return a local object from one of your methods, cant really tell
nice to know your computer is caller zonker...or something is...server maybe

It looks like the program might be deleting the same pointer twice...if I had to guess. Post your code if you want real help.
It took me a while, the error was in my header definition file and the compiler didn't catch it till I ran the program and a few logic errors.... Thanks though... I might need some more help later.
