That certainly sounds very much like the behaviour I'm seeing, except... 
it happens whether or not the code is compiled.

If I run GHCi with nothing compiled, it crashes. If I compile all the 
modules and run GHCi, it crashes. If I make a stand-alone executable and 
run it, it crashes.

Anyway, I shall try 6.10.3 and see what happens.

PS. Is there a ticket for this? I mean, it seems to be fixed, but we 
should probably still record it somehow?
