I could confirm the problem for the current development version, the CRAN version, both under ubuntu 16.04 with R 3.4.1 and Windows with R 3.3.3.
While this might point to a C memory allocation problem, debugging with valgrind didn't produce any errors.
The following code doesn't cause the crash, so it's definitely the object creation that messes things:

The following piece of code causes a hard crash very often (not always):

Maybe I am just reporting known behaviour?
