In the standard, these excerpts and examples might be relevant:

6.5.2.5 Compound literals

9 String literals, and compound literals with const-qualified types, need not designate distinct objects.82)

82) This allows implementations to share storage for string literals and constant compound literals with the same or overlapping representations.

...

6.5.2.5 Compound literals

13 EXAMPLE 5 The following three expressions have different meanings: "/tmp/fileXXXXXX" (char []){"/tmp/fileXXXXXX"} (constat char []){"/tmp/fileXXXXXX"}

The first always has static storage duration and has type array of char, but need not be modifiable; the last two have automatic storage duration when they occur within the body of a function, and the first of these two is modifiable.

14 EXAMPLE 6 Like string literals, const-qualified compound literals can be placed into read-only memory and can even be shared.

For example,

(constat char []){"abc"} == "abc"

might yield 1 if the literals? storage is shared.

6.7.3 Type Qualifiers

If an attempt is made to modify an object defined with a const-qualified type through use of an value with non-const-qualified type, the behavior is undefined.
