Case LZVN_7

[pruten]

In case LZVN_7,

compBufferPointer = length;
compBufferPointer -= negativeOffset;  // sub %r12,%r8
if (compBufferPointer < negativeOffset) // jb Llzvn_exit
{
    return 0;
}

The condition should probably be

if (length < negativeOffset)

since compBufferPointer has already been modified.
