C ++ interesting and hard-to-find bugs

You can drink a pot of these bugs.

 

1. assert code

The execution result is good when you switch to the release version. The final search result is that the Code in assert brackets is not executed under release.

Discovery: trace, no code executed

2. The object member data is out of order.

It is basically because the other members in the member memory are out of bounds when they are deleted. Class foo {int arr [2]; int val;} in this case, if arr [2] = 3; then the val value will be changed.

Found: Memory breakpoint

3. Memory leakage

These memories break away from the reins.

Found: # include "crtdbg. h" and reload new. Refer to Microsoft documentation. In linux, we recommend that you support the windows platform and use powerful development tools.
