How to investigate a null pointer or null address

A number of examples and scenarios are provided to help you learn how to investigate a null pointer or null address that is detected.

Null pointer in a header file
If the compiler-generated object is shown in the log entry, the offset in the null pointer detection log entry might not match the listing.
Null pointer in optimized code
When your C/C++ code is built with optimization, the null pointer detection log entry does not have the source line number.
Null pointer in a switch statement
A null pointer detection event that occurs during processing of a switch statement might not be indicative of a problem.
Null address in a macro call
Learn how to investigate a null address detection event that is reported in a macro call.
Null pointer code example
A code example is provided to illustrate a null pointer detection event that occurs because a return value is not appropriately processed from a C/C++ function.
