error

Hi
What does the following error message mean?

*** glibc detected *** double free or corruption (out): 0x0804d0d8 ***
Aborted
SHuo

It sounds like you are deleting a pointer twice. Are you using dynamic memory (new/delete)? Are you using classes? Are you using them together without a copy constructor and copy assignment operator?

To illustrate with code.....

Code:

...
string *s = new string("Deleted 2x.");
delete s;
delete s; /* DANGER, WILL ROBINSON! */
...

This is something dangerous that should not be done.
