Gregory, thanks for the quick assistance.
If I manage to press ctrl-c while still in rpy.py:__call__(), I can get
back to the python shell, and get a segfault at exit from this shell.
At other times, it will segfault immediately. Pressing ctrl-c a second
time in rapid succession seems with my small samples to produce the
issue more frequently.
I realize this doesn't resolve your question with more than a
"sometimes". Is there a case that might test this more definitively?
