Other than the "x" in the "0x" prefix to denote a hexidecimal value,
there are no "o" (oh) characters in hexidecimal values.  That is the
problem when describing an error message: you get it wrong and/or you
show it incomplete.  Don't describe an error message.  Don't summarize
it.  Copy and paste the error message in its entirety.
