      Trac #17785: crash in multipolynomial substitutions · ae128a30
      Release Manager authored
      The substitution code for multipolynomial (using Singular) results in a
      SIGSEV. For example, with `R.<x,y,z> = QQ[]` and any of
      {{{
      x.subs(None,y=x,x=0,z=y)
      x.subs(None,x=0,y=x,z=x)
      x.subs(None,x=0,y=0,z=x)
      x.subs(None,x=0,y=0,z=z)
      }}}
      Though, if we do not mix integer and variable in the substitutions it
      seems to work fine
      {{{
      sage: x.subs(None,x=0,y=0,z=0)
      0
      sage: x.subs(None,x=z,y=x,z=y)
      z
      sage: x.subs(None,x=x,y=y,z=z)
      x
      }}}
      And the following also works
      {{{
      sage: x.subs(None,x=0,y=x,z=0)
      0
      sage: x.subs(None,x=0,y=y,z=0)
      0
      sage: x.subs(None,x=0,y=z,z=0)
      0
      sage: x.subs(None,x=y,y=z,z=0)
      y
      sage: x.subs(None,x=y,y=0,z=0)
      y
      sage: x.subs(None,x=z,y=0,z=0)
      z
      }}}
      -------
      
      Original report
      
      The following code gives a coredump in Sage-6.5.rc3:
      {{{
      a11,a12,a13,a21,a22,a23,a31,a32,a33 = allvars =
      var("a11,a12,a13,a21,a22,a23,a31,a32,a33")
      P=PolynomialRing(QQ,allvars,order='degrevlex')
      P.inject_variables()
      A=matrix([[a11,a12,a13,],[a21,a22,a23,],[a31,a32,a33]])
      A.subs(a11=a13,a21=-a23,a31=a33,a22=0)
      }}}

      Trac #19781: Move broken optional packages to experimental · b39fa51c
      Release Manager authored
      The following optional packages are broken and should either be fixed or
      moved to experimental:
      
      * `cryptominisat`: crashes Sage on 32-bit.
      * `lie`: a very arcane build process (copies over the complete build
      directory and requires `bison`).

      Trac #15348: "R.<a> =" syntactic sugar incorrect for EquationOrder · e5af38dd
      Release Manager authored
      After typing
      {{{
      sage: f = x^2+1
      sage: R.<i> = ZZ.extension(f)
      }}}
      I expect variable {{{i}}} to be the element of {{{R}}} named {{{'i'}}}.
      However, it is not. It is the element 1.
      
      This is due to the generators of an order in Sage being its //module//
      generators (as noted by {{{EquationOrder?}}}):
      {{{
      sage: R.gens()
      [1, i]
      }}}
      
      We fix this by redefining `_first_ngens()` (which is what the preparser
      uses to implement the `R.<x> =` syntax) to use `_defining_names()`,
      which we override for orders.

      ------------------------------------------------------------------------
      Unhandled SIGSEGV: A segmentation fault occurred in Sage.
      This probably occurred because a *compiled* component of Sage has a bug
      in it and is not properly wrapped with sig_on(), sig_off().
      Sage will now terminate.
