According to
http://sourceware.org/gdb/current/onlinedocs/gdb_34.html#SEC708
the format is correct.
Whether the values are correct I can't say (an address of 1 seems wrong,
whether the size is correct depends on what 'x' is).
The response is E10 indicating an error, perhaps it's complaining
about the bad address.
