When you're in an earlier thread, "$eip" refers to that thread's
return address.  Which in turn refers to a location on the stack where
it is saved.  You're talking to a core file, so GDB can not write to
memory.

Honestly, I'm surprised that it works from frame 0 either.  I would
have expected writing to "registers" to fail.
