It's supplied by sssd-client. I tried installing sssd-client-debuginfo but it is already installed. I don't remember doing that. Sigh... Somehow libnss_sss.so is referenced by bash? That's what gdb thinks.

Yep, it needs it to get access to user and group data for things like tilde
expansion.

The trace you sent shows readline waiting in pselect for user input, so it
must be after the directory read was interrupted.

The only thing I can suggest is to defer the attach in gdb until bash
appears frozen. That may not work, but it's better than what you got.
