Incorrect implementation of the grouping variable in the function glmer crashes R

a small example:

a<-data.frame(b=rpois(1000,10), c=gl(20,50), d=rnorm(1000,3), e=rnorm(1000,5), f=rnorm(1000,2)+5);
glmer(b~d+f|c+(e), family=poisson, data=a)

It crashes R on debian linux (2 independant systems) as well as windows

The correct function usage is:
 glmer(b~d+f+(e|c), family=poisson, data=a)

I suppose it should just eveluate as wrong usage of a function but should not crash R
