Correct. I am not using libsingular here.
However, it seems it is not so easy to reproduce. When one simply has
a while-loop in which one does something like
R = singular.ring(0,'(x,y,z)','dp')
I = singular.ideal(['x*y','y*z','x+y+z'])
over and over again, than no bad things happen.
So, meanwhile I wonder if the problem is unrelated with the
autogenerated variables -- it could very well be my own fault. I
realise that frequently I do things like
singular.eval('ideal foobar = x*y,y+z')
without checking whether foobar is already defined.
Singular issues a warning in those cases ("redefining foobar"). But
could this be a real problem?
Anyway. I just wanted to know whether other people have met a frozen
Singular and can give me a hint, before I spend too much energy in my
bug hunt...
Thanks
Simon
