  OK, on closer inspection: the problem is simply that
lme4 is complaining that it's expecting the response to be
numeric: class "labelled" is not "numeric".

A simple workaround is
glmer(as.numeric(InInt)~speciality+position+stkperyr+conf+
   age+years+risk+stktype+(1|pid),data=dord4mod,family=binomial)

The development version of lme4 doesn't appear to hit the
same problem, but runs into a PIRLS problem at some point later
in the code you sent me (with ...

dord.glmer <- glmer(InInt~speciality+position+
 stkperyr+conf+age+years+risk+stktype+(1|pid),
   data=dord4mod,family=binomial)
)
