Error description

  • Access to static data in AMODE64 is loading a Q-CONS value using
    an 'L' instruction, which performs a 31-bit load and does not
    modify the higher order bits in the 64-bit register.  If the
    register was previously used, and the higher order bits
    modified, the loaded value via 'L' may be invalid.  The higher
    order bits should be zeroed out via the 'LLGT' instruction.
