Yes, this makes perfect sense to me.
Loading a compile file executes arbitrary code and that
can call compile.

In my source that is line 342.
What I normally expect is that errors in compiling or loading come
from the previous line,
(++ RelAdder 'StructProp 'AddStructProp)
which is the first ++ in the file.
Perhaps the two lines are being processed together?

++ is a macro that calls translateupdate (all this in transact.lsp)
and that calls getupdate.
Thanks for your help.
