  # Since v1.5.1, libjpeg-turbo uses the separate non-fancy upsampling and

  # YCbCr -> RGB color conversion routines rather than merged upsampling/color

  # conversion when fancy upsampling is disabled on platforms that have a SIMD

  # implementation of YCbCr -> RGB color conversion but no SIMD implementation

  # of merged upsampling/color conversion.  This was intended to improve the

  # performance of the Arm Neon SIMD extensions, the only SIMD extensions for

  # which those circumstances currently apply.  The separate non-fancy

  # upsampling and color conversion routines usually produce bitwise-identical

  # output to the merged upsampling/color conversion routines, but that is not

  # the case when skipping scanlines starting at an odd-numbered scanline.  In

  # libjpeg-turbo 2.0.5 and prior, doing that while using merged h2v2

  # upsampling caused a segfault, so this test validates the fix for that

  # segfault.  Unfortunately, however, the test also produces different bitwise

  # output when using the Neon SIMD extensions, because of the aforementioned

  # optimization.  The easiest workaround is to use the old test from

  # libjpeg-turbo 2.0.5 and prior when using the Neon SIMD extensions.  The

  # aforementioned segfault never would have occurred with the Neon SIMD

  # extensions anyhow, since merged upsampling is disabled when using them.
