I just had SageMath 9.2 crash, so I tried installing 9.3. Alas, I
get the same problem. The offending command is pretty innocuous:
sage: plot(ln(1+x),(-1,5))
The Sage window then crashes. In the notebook I get a message
that the kernel just died. Running it in the Sage Terminal, sage
crashes and leaves this message behind:
------------------------------------------------------------------------
Unhandled SIGSEGV: A segmentation fault occurred.
This probably occurred because a *compiled* module has a bug
in it and is not properly wrapped with sig_on(), sig_off().
Python will now terminate.
------------------------------------------------------------------------
/opt/sagemath-9.3/src/bin/sage-python: line 2: 1535 Segmentation
fault (core dumped) sage -python "$@"
Any ideas as to what is going on?

Update: the problem is machine-dependent. On one Dell laptop, plot works with no problem. On a different one, big crash.

Hi, I do have the same problem. I can't use plot() - not even a plot(1) with a constant . I am running Sage 9.3 on Windows 11 and Surface Book 3. I understand that the problem will not be solved until Sage 9.5. But I need the plot() function now. Is there a workaround or another way to plot data?

Not on my machine. I even tried something like P=plot(something) followed by P.save('filename'). The assignment works fine, but when it tries to save the Sage kernel crashes.
The only workaround I have found is using SageCell. But that is not very convenient if I need to save the result.
