I've got some time today to look at building readline, but for the life
of me, I can't figure out what I'm supposed to be debugging. You have
so many emails saying "see this earlier URL" that I am lost in what you
are saying is wrong or how to reproduce it.
I'm currently testing with:
libreadline7 7.0.3-3 (or self-built)

Thanks again for trying to narrow things down. I have recompiled
readline locally with optimizations turned off (so it's easier for me to
see what's going on), and am set up to run gdb on bash with a given
readline executable installed. If you have really narrowed the problem
to rl_insert(), that's at least something I can investigate.
But where I'm stuck now is what works for you and what you think is
wrong. Is this something where I can start bash under mintty, or do I
have to start under cmd? Right there, I already see a difference with
the two environments. Starting from cmd, I did:
c:\cygwin\bin> od -tx1
00000000 ce a9 0z
so I did indeed insert GREEK CAPITAL LETTER OMEGA U+03A9.
But trying the same thing under a bash session in minty shows:
0000000 c3 aa 0a
so that is not the same character. I'm not sure if a code page change
is supposed to alter what I see.
So I'm back to cmd to try and debug things. Next, I tried:
and again got Ω; pressing <enter> complains that ./dash: 1: Ω: not found
However, when I try:
c:\cygwin\bin> .\bash --norc
the display shows :\251
and hitting <Enter> wipes out that display without doing anything. So I
_think_ I'm running into the problem you're describing, but want to make
sure, since it is different based on whether I started bash from cmd or
