32 bit R and 64 bit R: output differs

I've made a script to predict wage based on the variables:gender, age and education. I use the rpart function. When i run the code in 32-bit R, the output differs from the 64-bit R version. The difference is not dramatically, but I can't decide which output is correct.

The data set is quite large (10,000+ entries). because of privacy reasons i'm not permitted to share data/results.

this is the code i use:

set.seed(1234)
tree <-rpart(wage ~  gender + age + education, method='class', data=Data, control=rpart.control(minsplit=1, minbucket=1, cp=0.002))

How can i get the correct output in both versions of R? Can the GMP package help me? If yes, how?

You need to manually set the seed parameters. Like this ...

set.seed(1234, kind = "Mersenne-Twister", normal.kind = "Inversion");
mean(rnorm(1000))

This gives the same result on 32 and 64 bit.
