But that means: We finally have a system where it happens ''with
#715+#11521 only''! So far, we only had Volker's patchbot, which produced
segfaults when other patches were applied on top of #11521.
Hence, hope increases.

Did it really fully pass and you came back to your shell prompt, or did
the tests pass and there was a segfault when Sage shuts down?
Can you produce a backtrace, say, by using gdb? Or can you give me access
to the machine, so that I can do some experiments?
Best regards,
Simon
