about realrad

Dear All,

When we set

Code:

LIB "realrad.lib"; ring r = 0, (c, b, a), lp; ideal i = a2-2 * b2 + c, a-b2 + a * c3, a + b * c;

the following process gets stuck.

Code:

realrad(i);

As a workaround, for example, there is

Code:

list(apply(facstd(i), realrad));

However, please let me know why realrad alone does not work.

Regards,
Kahan
