It occurs to me that this *might* be an instance of the (very technical) bug fixed by https://github.com/sagemath/cysignals/pull/108, and included into Sage 8.7 by https://trac.sagemath.org/ticket/27070 If so, it's occurring in a context that I didn't previously know about but it's not impossible, especially if there is BLODA involved. If nothing else it could be masking a different bug. I haven't made a Windows release for Sage 8.7 yet, in part because it needs some additional patches that were not included in the main 8.7 release tarball. I'm not happy about that but it can be dealt with by updating the build tools for the Windows release to include additional patches; I just need to do it. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
