[sage-devel] Re: Segmentation Fault

I'm surprised that this hasn't been reported previously, because we can get a crash even without atan or any division: sin( x*(x+1) - x^2 - x ) # this crashes sage This also crashes with sinh or cos or tan in the place of sin, but not with exp or log. PS I verified on CoCalc that this is no

Localized a bit further: var("q A") p = A*(1+1/A)-A-1 V=(q^p)._maxima_().rectform() after this, V._sage_() crashes, and I think it's the same crash as above. Transcribing what V is in maxima, we get: I*sin(atan2(0,q)*((1/A+1)*A-A-1))*abs(q)^((1/A+1)*A-A-1)+cos(atan2(0,q)*((1/A+1)*A-A-1))*abs(q)

[sage-devel] Re: Segmentation fault factoring a multivariate polynomial over IntegerModRing

It looks like this problem is going to be fixed by the upgrade to Singular 4.1.3 (#25993). sage: R. = Integers(7)[] sage: p = x**2-1 sage: p.factor() (x + 1) * (x + 6) There is another segmentation fault related to the non-commutative subsystem Plural, though, causing a doctest

[sage-devel] Re: segmentation fault in sage 7.3

I have both, one locally compiled version, which I upgraded from 7.x, and one freshly installed binary. Same problem on both. Seems that save_session() and load_session() causes all sorts of problems, especially when using jupyter. On Thursday, September 8, 2016 at 11:45:32 PM UTC+2, leif wrote
