#365 new bug

morsesplit in classify.lib crashes

Reported by: steenpass Owned by: pfister
Priority: minor Milestone: 3-1-4 and higher
Component: singular-libs Version: 3-1-3
Keywords: classify.lib, morsesplit Cc:

Description

> option(noloadLib);
> LIB "classify.lib";
> ring r = 0,(x,y,z),ds;
> morsesplit(xy+z2);
   ? div. by 0
   ? error occurred in or before classify.lib::Morse line 1683: `          P = P / number (2 * a);`
   ? leaving classify.lib::Morse
   skipping text from `;` error at token `)`
   ? leaving classify.lib::morsesplit
> 

It is easy to see that the result should be 0: By sending x to x+i*y and y to x-i*y, we get x2+y2+z2, so the residual form is 0.
