Even if you can't nail down the specific instances when this occurs, a
few examples of when it does (or has) or doesn't (or hasn't) would help
someone help you.
You said "bash" and "terminal emulator," so I could probably assume
Linux or BSD, but what OS(es), desktop environment(s), and/or window
manager(s) are you running or have you tried?
What made you think that n-key rollover would make a difference? Are
you running assistive software, or some sort of uncommon hardware or I/O
subsystem? Is it some kind of virtual machine?
