Re: [sage-support] multivariate polynomial factorization over GF(2)

[Martin Albrecht]

Dear [libsingular-devel], the following bug was reported at [sage-support]:


> ring r = 2,(t,x),dp;
> poly g = t^16*x + t^10*x + t^9*x + t^6*x + t^5 + t*x + x^2;
> factorize(g);
Singular : signal 11 (v: 3133/ 14405 ):
current line:>>factorize(g);<<
Segment fault/Bus error occurred at a776a01 because of 10283 (r:1340008265)

Hi Martin,
this one is fixed as well in Singular 3-1-4-4.
