plotting discontinuous functions

[Fernando Gouvea]

Running Sage 10.2 on Ubuntu in WSL...

When I try to plot certain discontinuous functions I get long error messages ending with

TypeError: ECL says: BINDING-STACK overflow at size 10240. Stack can probably be resized.
Proceed with caution.

For example, this happens when I try to plot (-1)^floor(x)*frac(x) and for functions defined using piecewise. Any hints?

To be human is not simply to possess the capacity to make rational
choices; it is to possess the capacity to make those choices potent.
And that potency will change you over time, not only in obvious
external ways, but internally too. Those changes can be for good or
evil, of course, but whatever they are, they are obviously
potent. They change you.

I don't think many people run 10.2, and it might be that your problem is fixed in 10.6.
Can you post a complete reproducer for the problem?
