As well it should.  This is the exepected behavior.  From the manpage.

    The mktemp() function takes the given file name template and overwrites a
    portion of it to create a file name.

The routine is attempting to write to a constant string, which it can't
so it cores.  You need to give a writeable memory location to mktemp().
