This looks like (only) a part of a stack trace and in itself there's nothing wrong with the output. The numbered objects (#xx#) are printed to make it easier to figure out which variables point to the same object from local variables in the stack trace. Are you running with --trace-calls or some other non-standard flag? The --trace-calls option gives you a stack trace at every function call (just after the called function has been entered), which may look something like what you're describing.
