I compiled Python 3.13 (commit d86b494, the current tip of the 3.13 branch), and installed it into ~/opt/python313. When I run python3.13 with no arguments, I get this:
Python 3.13.0b1+ (heads/3.13:d86b494117, May 9 2024, 15:23:21) [GCC 13.2.0] on linux

IndexError: list index out of rangeand it exits with status code 1.
My terminal is currently 126 columns by 45 lines, and I have a custom PYTHONSTARTUP environment file pointing to ~/.python, which you can see in this GH repo. It sets up some conveniences for the old REPL (colorful prompt, rlcompleter-based tab-completion, persistent readline history).
Running PYTHONSTARTUP= python3.13 fixes the IndexError.
By commenting out bits of the file I can reproduce the IndexError with just this:
import sys
sys.ps1 = '\001\033[0;32m\002>>> \001\033[0m\002'
del sys
The \001/\002 characters are hints for readline to inform it that everything between them is a terminal escape sequence that doesn't advance the cursor, without which readline cannot correctly compute the width of the prompt and makes wrong assumptions about line wrapping.
The IndexError goes away if I remove all \001 and \002 characters from sys.ps1.
