Have a file containing a read error - say, just "stumpwm:read-command". Load it and catch the error, e.g. with
(handler-case (load file) (error (c) c))
and print the result with :escape nil (this was located via princ). I get this error:
#<SB-SYS:FD-STREAM for "file /home/aeshtaer/test.lisp" {100658C8A3}> is closed

What I expected: the error message to be printed. e.g. the same setup in CCL outputs «There is no package named "STUMPWM" .».
This does not happen with compile-file instead of load, or with :escape t.
I previosuly reported #1042610, which also involves SB-C::INPUT-ERROR-IN-COMPILE-FILE and a hairly loading situation. MIght be related.

As it says in the backtrace, I think the sort of problem is that sb-kernel:
