it's also not the problem of clang, i tried it on both compilers gcc and clang, and both of them segfault.

Please do not CC arches on your own.

Please make it impossible for normal users to use options that should have been enabled only for maintainers/admins.

The rule of the thumb is don't touch fields you don't *need* to.

But as for the problem, I can see the crash too.

Maybe it's polish locale related.

works fine for me

reporter's emerge info says he's using en_US.UTF8 locale.  what locale are you guys using exactly before you run `su` ?  post the output of `locale`.

[Comment 10 Aleksander Balicki 2011-09-29 08:38:05 UTC]

alistra@bialobrewy ~ % locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"

Well, from me segfault happens both in pl_PL.utf8 locale and with 'LC_ALL=C su'.

this still a problem with shadow-4.1.5.1-r1 ?
