If you haven't submitted a support request with Intel Online Service Center (https://supporttickets.intel.com/?lang=en-US), please do so - an ICE is always a compiler bug worthy of immediate attention. Thanks,

I had intended to add a few comments to my original submission but couldn't work out how to insert comments after the code. The originating program divides repeated tasks equally amongst a number of images, does the calculations, then combines the individual sets of results into a single object ready to be returned upstream. I found that the code was sensitive to details and could run successfully but could also result in an ICE, as demonstrated here, or compiled but then led to a run time error at the same offending line. I wasn't sure whether it was due to my misunderstanding of coarrays/allocatables/synchronization but the ICE suggested there was definitely some sort of problem with the compiler, perhaps one that went deeper than error diagnostics. I currently have free access to ifort (shortly to be ended) courtesy of the 'hobbyists' scheme originally set up by Steve a few years back. My license has now been changed to a 'student' license which being free does not offer OSC support, which is fair enough. Accordingly, my earlier submission to OSC was rejected but they suggested I submit it here so that is what I did.

It seems the right thing to do for Intel to allow any and all users, whether hobbyist or student or trial licensors, to report ICEs with their compiler at their OSC support site. Intel will then show in good faith to all their paying customers they truly believe in product stewardship and they intend to continuously and promptly improve their product.
Re: "they suggested I submit it here so that is what I did" - will wait to see if some Intel staff follows up on this ICE.
