no risk.
remember that

 char *foo = "For whom the bell tolls";

has the same effect as doing.

 char *foo;
 foo = "For whom the bell tolls";

as you see there's no heap memory allocation step,

It's just pointing the pointer to memory location, in this case the
location is that which the compiler creates for the literal string,

foo = foo + 1;
foo = NULL;

etc just modify where foo points, there's no risk of a memory leak until
you open that can of worms by using one of the memory allocation
functions....
