SYNOPSIS
        string *last_instructions (int length, int verbose)
DESCRIPTION
        Return an array showing the 'length' last executed
        instructions in disassembled form. If 'verbose' is non-zero
        (the default), line number information are also included.
        Each string is built as this:
          Opcode-Address: Opcode Operand Mnemonic (Stackdepth) Linenumber
        The Stackdepth information consists of two numbers <rel>:<abs>:
        <rel> is the relative stack usage in this function, <abs> is the
        absolute stack usage.
        The linenumber information is appended if requested and a new
        source line is reached. Also, calls between objects produce a
          Objectname Programname Linenumber
        entry in the resulting array (in verbose mode only).
        There is a preconfigured upper limit for the backtrace.
HISTORY
        Introduced in 3.2.1@34
        The absolute stack depth information was added in LDMud 3.2.8.
