| Priority: | minor | Milestone: | 4-1-0 and higher |
| Component: | factory | Version: | 4-0-1 |

Description
failing example:
ring rng =(7),(a,x,y,z,w),dp; ideal PS = -2*a*y*z^2-2*y*z^2+2*a*z-3*z-1, -2*x*w^2-3*a*x+x, -a*y^3+y^3+2*a-2, a^2+a+3; char_series(PS);
output:
zz_pX InvMod: can't compute multiplicative inverse Singular : signal 6 (v: 4010): current line:>>char_series(PS);<< Segment fault/Bus error occurred at 1591990 because of 206 (r:1413880267)

cannot reproduce it in the standard configuration (with flint 2.4.4, ntl 5.5.2), but the patch https://github.com/Singular/Sources/pull/658 seems to work.
