It's not triggered by fpregs.pas. It's triggered by importing one or 
more of FPViews FPVars FPDebug which suggests to me that it's in some 
common file that those three (but not FPConst) themselves import.

I wish I'd got one of my elderly ARM systems available, since it would 
be interesting to know if it happens on another architecture that's 
picky about alignment.

Work continues intermittently.
