Either the condition 'code_ll==(unsigned int)(-1)' is redundant or the
array 'LENGTHBASE[29]' is accessed at index 4294967038, which is out of
bounds.

On other hand this condition is tested within other scope:
"if(code_ll >= FIRST_LENGTH_CODE_INDEX && code_ll <= LAST_LENGTH_CODE_INDEX)"
with is already limited to (code_ll >= 257 && code_ll <= 285),
so it can't be -1 any way.
