Bug#1022564: locale related segmentation fault

[Aleksi Suhonen <debian-reportbug-2022@ssd.axu.tm>]

Package: libc6
Version: 2.35-3
Severity: important

I ran into this issue while updating packages on a Debian/sid machine, 
and the install scripts for "ntpsec" and "tzdata" started failing with 
segfault. I couldn't find a way to reproduce it on that machine 
immediately. I started suspecting the machine might be failing.

But then I ran into the problem on another machine that runs "bird" 
routing daemon, as its control program "birdc" also started segfaulting, 
but started working if I set LC_ALL=C. Then I found I could also get the 
install scripts on the first machine to work with LC_ALL=C.

So, steps to reproduce:

root# apt-get install bird
root# LC_ALL=asdf birdc

I'm sure there's a way to reproduce it without installing new packages, 
but rather than trying to find one, I thought I'd report the problem as 
soon as possible, because it smells to me like there might be some 
overflow involved...

Best Regards,
