Excellent, thanks! Mind closing the bug with the giac upload ? > but still, crashing is pretty bad : it should detect > the value is too low at startup and complain. The amount of stack needed depend on the computation the user requested, so it is the responsibiity of the user to set the stack size. However, the user can set parisizemax to allow PARI to increase the stack as needed up to parisizemax. If the stack is still too low, then you get an error that you can trap and recover from. It seems giac recovery code does not handle pari stack overflow correctly. This should be fixed, but this is not a RC bug in pari, and probably not a regression. Cheers, Bill
