The pointer checker is not supported on
The C and C++ language allows you to define arrays in another module with the
keyword. These arrays can be defined without specifying the dimensions.
Example: Creating an Undimensioned Array
The compiler allows more than one definition for externally defined arrays. During link time, the compiler uses the array definition with the largest bounds.
To check these arrays, the compiler defines a global symbol that marks the end of the array. However, checking undimensioned arrays can lead to a multiple defined linker error. To fix this linker error, do one of the following:
- Use only one array definition.
- Use the negative form of the[Q]check-pointers-undimensionedcompiler option to disable checking arrays without bounds.
This compiler option suppresses checking in the module that declares an array without bounds. The pointer checker will still check the arrays in modules that actually define the arrays with bounds.
