[sage-release] Re: Sage 8.9.rc1 released

Hmmm... This one is nasty...

On Debian testing running on core i5 + 8 GB RAM, upgrading from 8.9.rc0, I 
get:


Transient errors:

  src/sage/combinat/posets/posets.py               1 doctest failed
  src/sage/plot/animate.py                         7 doctests failed

  src/sage/interfaces/magma~free~.py               2 doctests failed
  src/sage/interfaces/mathematica.py               Timed out

Permanent errors, already known:

  src/sage/libs/eclib/interface.py                          1 doctest failed
  src/sage/rings/polynomial/polynomial~rationalflint~.pyx   1 doctest failed

New permanent errors due to aborts:

  src/sage/crypto/mq/sr.py                                   Killed due to 
abort
  src/sage/rings/polynomial/multi~polynomialsequence~.py     Killed due to 
abort
  src/sage/rings/polynomial/pbori.pyx                        Killed due to 
abort
  src/sage/rings/polynomial/polynomial~ringconstructor~.py   Killed due to 
abort
  src/sage/sat/solvers/dimacs.py                             Killed due to 
abort
  src/doc/en/reference/sat/index.rst                         Killed due to 
abort
  src/sage/sat/boolean~polynomials~.py                       Killed due to 
abort

Details in SageTstAborts (attached).

Looking at those details, in all but one case, the abort is a "length 
error":

  src/sage/crypto/mq/sr.py                                   terminate 
called after throwing an instance of \'std::length~error~\'
  src/sage/rings/polynomial/multi~polynomialsequence~.py     terminate 
called after throwing an instance of \'std::length~error~\'
  src/sage/rings/polynomial/pbori.pyx                        terminate 
called after throwing an instance of \'std::bad~alloc~\'
                                                             terminate 
called recursively
  src/sage/rings/polynomial/polynomial~ringconstructor~.py   terminate 
called after throwing an instance of \'std::length~error~\'
  src/sage/sat/solvers/dimacs.py                             terminate 
called after throwing an instance of \'std::length~error~\'
  src/doc/en/reference/sat/index.rst                         terminate 
called after throwing an instance of \'std::length~error~\'
  src/sage/sat/boolean~polynomials~.py                       terminate 
called after throwing an instance of \'std::length~error~\'


The exception in pbori.pyx, seems to be multiple errors.

I suppose tat something may be broken in my setup. Hints about how to 
unhose my system are welcome...

HTH,
