I'm not sure how that could be the problem. Nothing up there tries to
modify the buffer.
The *Messages* messages indicate that the error is occurring when
semantic-c is loaded. I suggest you set debug-on-error to t, so you'll
get a stack trace when the read-only error occurs. Then post the stack
trace here.
