Enable null-pointer checking

Syntax

` -enullptr

`

Description

The -enullptr compiler option enables null-pointer error checking in run-time code generation. A run-time error is generated if an attempt is made to dereference a null-pointer to a value, or call a null function pointer.

-enullptr is automatically implied by the -exx option.

__FB_ERR__ can be used to determine in user source code if the -enullptr option was specified or implied on the command line.
