Because the storage duration of the compound literal is associated with the for loop that contains it, dereferencing ints in the second loop results in undefined behavior 9 (Annex J of the C standard Standard [ISO/IEC 9899:2011]).
Even if the region of memory that contained the compound literal is not written to between loops, the print loop will display the value MAX_INTS-1 for MAX_INTS lines. This is contrary to the intuitive expected result, which is that the integers 0 through MAX_INTS-1 would be printed in order.
