IMO, the vast majority of gdb users will not care, or even understand 
what the instruction means. Most of the time, the only reason I would
personally land in code that doesn't have any debugging info is when
attaching to a program, loading a core file, or pressing control-c.
In such cases, the first thing I usually do is "break ...; continue".

I have very very very occasionally done stepi's that got me inside
such code, but in that case, I use a special user-defined command
that does the stepi and then prints the instruction.

It's not just about the bug, actually - I wasn't suggesting that
we change the default as a way to make it go away. Rather, I think
that this default setting will be useful to only very few people,
while at the same time creating the equivalent of noise for the
rest of the population. This is why I maintain my suggestion of
changing the default to "off".
