Agree.  I want to do that.  I'll try to be more measured with my
language.  However, refusing to talk about this saying that this was
discussed in C17, doesn't seem like an in-depth analysis.

Can we please do an in-depth analysis, forgetting any mistakes on either
side that might have been made prior to now?  I'm interested in fixing
this, and am trying to find the best solution.  I'd appreciate some
collaboration.

Some of us think that this is not dangerous, and can be fixed in glibc
without any problems.  I'm, just like everybody, not interested in
making things worse, so it would be great if you could show how
improving the behavior of glibc could make things worse.  Or maybe tell
me what you need so that we can agree to a path to a fix.

I don't use short-form social media.  I was actually referring to
senior engineers that often publish on stackexchange and similar sites.
Engineers that have taught me a lot of what I currently know, and which
have a deep understanding of C.

Have a lovely day!
Alex
