No, It's not a bad practice, it's an IAR violation to C language standard, see 
6.5.9 Equality operators:

-----------
Two pointers compare equal if and only if both are null pointers, *both are 
pointers to the same object* (including a pointer to an object and a subobject 
at its beginning) or function, both are pointers to one past the last element of 
the same array object, or one is a pointer to one past the end of one array 
object and the other is a pointer to the start of a different array object that 
happens to immediately follow the first array object in the address space.
