It's certainly not the intention to give segfaults for that reason...

However, the same pattern could occur from PROTECT errors in your C
code, triggered by a garbage collection at just the wrong moment
(which could be different on different OSs). 

You should rerun the relevant testscript under "R -d gdb" and see
exactly where the segfault occurs.
