bug report |
Hi, Here are two bugs I've stumbled upon one year ago. This report applies to 2.1.4 as well as 2.1.5. 1) The following program makes GP segfault: subst("a", a, b) 2) The following program makes the stack overflow: x y valuation(Mod(x, x^2 + 1), y) 3) A variant on the previous bug: t w a = nfroots(nfinit(w^2 + 1), t - 1)[1]; \\a = eval(Set(a))[1]; valuation(a, z); It produces a stack overflow, but uncommenting the fourth line solves the problem. --Olivier Wittenberg
