Notwitstanding that there may be issues with some OS X builds of 
groff, as shipped by Apple, this one is completely reproducible with 
groff-1.19.2 on GNU/Linux.  It looks like a bug in e.tmac, (in its 
page transition handling specifically); trivially converting the OP's 
test case to use s.tmac instead, produces output as expected.

Just for the record, the OP's test case did *not* crash nroff; it 
simply caused nroff to give up on his input stream, reporting:

  troff: fatal error: input stack limit exceeded 
  (probable infinite loop)

That is a strong indicator of a probable infinitely recursive macro 
loop, induced by the specific set of conditions imposed by the OP's 
input sample.
