Martin Panter added the comment: I think Victor may be on the right track. Since the macro contains two newlines, a single call to rl_callback_read_char() is going to produce two calls back to the rl_callback_handler_install() handler to receive each line.
I can make the example from the Readline documentation <https://cnswww.cns.cwru.edu/php/chet/readline/readline.html#SEC43> crash the same way that Python does. First, add a macro to ~/.inputrc, which causes an exclamation mark (!) to enter two lines at once: "!": "exit\ncrash\n" Now, typing an exclamation mark will cause the example program (and Python!) to crash. In the description of rl_callback_read_char() <https://cnswww.cns.cwru.edu/php/chet/readline/readline.html#IDX335>, it says “If the ‘lhandler’ function returns . . .”. That seems to be hinting at using something like setjmp() to avoid the function returning, which might help, but I am not sure. ---------- nosy: +martin.panter _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25259> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
