I can reproduce the problem and it looks like a bug to me. However it
is very easy to work around it till someone from StataCorp either tells
us that it isn't a bug but that we are doing something dumb or that
they will fix it: Use -logit- instead of -logistic-. See the example
below:

*---------------- begin example ---------------
sysuse auto, clear
recode rep78 1/2=3

// Works:
xi: bootstrap _b, eform reps(100) dots: ///
    logit foreign i.rep78 price

// Does not work:
xi: bootstrap _b, eform reps(100) dots: ///
    logistic foreign i.rep78 price
*------------------ end example ---------------
(For more on how to use examples I sent to the Statalist, see
http://home.fsw.vu.nl/m.buis/stata/exampleFAQ.html )

Hope this helps,
Maarten
