Hello, This looks very much like a bug I fixed recently (Trac ticket #15446). Could you check if the bug still exists in the latest development version? Peter I'm trying to find asymptotic bounds for the number of polynomials of degree $n$ and height $\leq N$ with a specific Galois group

The sage variable in various interpreters is used to keep references to whatever is wrapped in Sage Python objects. Have you considered using the pari shared library (pari in Sage) instead of the gp interface? Its much faster, too. -- You received this message because you are subscribed to

Each instance of the pari/GP interpreter interface has its own list of variable names, which is initialised to length 1024 but extended (by doubling) as needed (see src/sage/interfaces/gp.py). It seems that this extension does not work after a certain number of doublings. This may be some
