Hey yo --
gdb is seg-faulting immediately whenever its run with --noasync.
I have an old build from the beginning of March that doesn't
do it (nor do even older ones), so it's probably a change
from between then and now.
It crashes in display_gdb_prompt, as called from
tui_command_loop. Here's a backtrace.
