That is something I do not know yet, since the only information the server
gives is this:

I'll probably end up debugging the C code, but since the only difference is
using Free() vs free() on exactly the same objects, I suspected a mis-usage
of the R commands.

The same setup passes with no problems on my local MacOS, but the errors
still seem to occur on the Windows setup from r-hub.

Best wishes,
