Dear all, Substitution on multivariate polynomials is leaking memory (https://trac.sagemath.org/ticket/27261). This can actually crash sage if used a lot (with a memory overflow error from singular). The code of subs and __call__ use some low-level calls to the singular library and this is likely to be the origin of the problem. Unless somebody knows the code or want to dig in, I propose to switch to naive symbolic evaluation. This is infinitely slower but at least does not leak memory. Please have a look.
To my mind, it would make sense to add this to the 9.3 release. Best Vincent -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
