    ANSI/ISO 9899-1990, Section 7.10.3.3 clearly states:

        "The malloc function returns either a null pointer
         or a pointer to the allocated space."

    There are no "undefined" possibilities here. Aborting the program
    on a failure to allocate memory is pretty clearly a violation
    of the standard, which requires the malloc function to
    always return.
