Interesting.  Of course, if you had used raw images, this wouldn't
have happened.

I do this kind of thing all the time, and I have no issues.  As I
mentioned earlier, I do three shots at 3 EV intervals: +4.7 EV, +1.7
EV and -1.3 EV.  I take a separate shot with the sun blanked out and
then merge them, using only the area round the sun for the shot that
includes the sun.  This is not for exposure purposes, but it gets rid
of flare in the shadows.

I believe to have figured this out -* colour space*.

Working on other scenes in the meantime I found that jpgs from my camera 
were written in AdobeRGB97, which is proprietary. Using 16bit TIFF files, 
exported from RAW, resulted in the same issue but once those were written 
in sRGB colour space solved the whole thing.

It would be best if someone could confirm this.
