Oh, I have noticed that 4.5 has different problem, involving assembler errors.
>From attached assembler:
/APP
# 912 "swscale_template.c" 1
lea 11*8+4*4*256(%rdi), %rdx
<stuff deleted ...>
>>> cmp %r15d, %rax
<more stuff deleted ...>
jb 1b
# 0 "" 2
/NO_APP
This simply means invalid asm constraints or operand prefixes in asm.
Thus, WONTFIX for 4.4 and INVALID for 4.5.
