dereferences a null pointer. I did not have any problem with any compiler yet. It works! But is this guaranteed? Try uping the optimization. A good compiler will know that "this" can never be null, and optimize out the test, always executing the true branch. Throw in multiple inherita...

A pointer and the pointed-to data are both checked for NULL correctly, but a debug/warning message that is printed uses the pointer that might be NULL, as shown in the following example:For example if varA is NULL:Copy if (NULL == varA || NULL == varA->part1) printf("Bad arg ...

[Frames below may be incorrect and/or missing, no symbols loaded for kernel32.dll] After a lot of reading, I have concluded that I am dereferencing a Null Pointer and then trying to use it after this. However, nowhere in my code do I overtly set a pointer to 0 or NULL. I've read...
