I'm surprised you see a difference. This code is supposed to be
platform independent. So I guess you need to examine all the places
in xdisp.c which are "#ifded NS" or "#ifndef NS".

This is expected, and not a bug: IT_STRETCH means we are producing
stretch glyphs "out of thin air", this happens when processing 'space'
display properties and line-prefixes. When we display a TAB, we
produce the stretch glyph from a TAB, which is a character.
