Bug#57622: strcoll segfaults

[Zdenek Kabelac <kabi@informatics.muni.cz>]

Package: libc6
Version: 2.1.3-2
Severity: important

Hi

After today's upgrade (2000-02-09) of glibc sort is generating coredump
As sort is dated 1999-08-09 I assume this bug is cased by some internal
glibc fault.

I've added program which creates unsortable file for sort:
(yes I know the line has 180KB - but it used to work)

Important thing seems to be which locales are being used

It segfaults for cs_CZ, en_US, pl_PL,...
It works ok for C, en, ...
