#721 closed bug (fixed)

a size()-misusage bug in 'gitfan.lib'

Reported by: jakobkroeker Owned by: somebody
Priority: minor Milestone: 4-1-0 and higher
Component: dontKnow Version: 4-0-2
Keywords: Cc:


'gitfan.lib' is not ready to be used as a black box component: it contains at least a known size()-misusage bug:


  ring R = 0,(T(1..4)),dp;

  ideal I = T(1)*T(2)-T(4) , 1;
  ideal J = 0,I;

  intvec w = 0;
  isAface(J,w); //1, wrong !

Remark: there are much more potential size()-misusage bugs in Singular library code, see

If someone thinks that I'm too picky or the issue 611 is too abstract, here are two examples(bugfixes) that show size()-misusage impact:
