Bash Version: 4.4 Patch Level: 12 Release Status: release Hi, On Ubuntu Artful (glibc-2.26), this tiny snippet reproducibly crashes bash: LC_ALL=en_US.UTF-8 # or any other UTF-8 locale echo -e '\ud800' # or any other lone high or low surrogate LC_ALL=en_US.UTF-8 # or any available locale I've discovered it in gnome-terminal. After sourcing /etc/profile.d/vte-2.91.sh [1] and manually echoing a surrogate, from then onwards the prompt takes a long time to display and I keep getting system-crash-notification's "System program problem detected" popup, as the subshell crashes at the locale change in __vte_urlencode(). [1] https://git.gnome.org/browse/vte/tree/src/vte.sh?h=vte-0-50 Thanks a lot for looking into this, egmont
