Evidence of it randomly pass/failing, if you're into that sort of thing. Nothing happened between these commands. I just hit up and enter:

This might not be entirely related, but I have just seen the same test fail with another error on a patchbot:

sig_on()
SystemError: calling remove_from_pari_stack() inside sig_on()
I've been trying to track this down for some time without luck. The important ingredients seem to be,
-O0
inCFLAGS
andCPPFLAGS
.-p2
but even then it's not always reproducible (so I can't really be sure how critical the ingredients above are). This is on an unmodified 9.5.rc3.
Also note that the doctest is trying to catch the very exception that kills it.
