Hi,
What do you mean by crash? Could you copy paste the *full* traceback
that you obtain?

Hi all,
I'm trying to solve a system of 1st order ODE using desolve_tides_mpfr()
arbitrary precision module. My script crashes at the external gcc call.
So I try this very simple example I found from a tutorial in a website. It
also crashes at the same gcc call. I test it in the SageMath online cell
server, it crashes as well, so it's not just my code or my setup.
Could somebody help with this example? Is this a bug, or the script is
wrong?
Thank you
Toan
