[gentoo-user] Anyone else having a problem with bash?

[walt]

My bash problem started a few weeks ago but I can't remember when.
This problem is intermittent and hard to reproduce.  I'm seeing it
maybe less than ten times per day but often enough to be really
annoying.

This is the problem:  occasionally bash gets in a state where it stops
echoing the characters I type.  The commands I type continue to work
properly and I can see the output from them but I can't see the commands
on the screen as I type them.

So far I've seen this problem start *after* some bash command has
finished executing, e.g. after doing 'git diff'.  It never happens when
I open a new xterm, before I run a command.

I emerged app-shells/sash and I don't see the problem there, so I think
this is a bash problem, but I'm just guessing.

Any ideas?
