#555 closed bug (fixed)

bug in Ehv::compareLists

Reported by: kroeker@… Owned by: pfister
Priority: minor Milestone: 4-1-0 and higher
Component: singular-libs Version: 4-0-0
Keywords: compare different primary decomposition algorithm results Cc:

Description

Here is the failing example: 

LIB("ehv.lib");
ring r  = integer, (x,y),dp;

list L1 , L2 , tmp;

tmp[1] = ideal(0);
tmp[2] = ideal(0);

L1[1] = tmp;

tmp[1] = ideal(x);
tmp[2] = ideal(x);

L2[1] = tmp;

L1;
L2;

compareLists( L1, L2 ); //=1, wrong!

A statement 

 if (size(N)<s1) {  return(0);}

would fix the issue.

Also the routine should be renamed, since it does *not* compare lists.
