It's quite recent actually --- according to http://sourceware.org/cgi-bin/cvsweb.cgi/libc/intl/dcigettext.c?cvsroot=glibc the problem was introduced into upstream sources on 24-Sep. I was a bit confused yesterday because I'd been looking at another lock used by the same routine that's been there much longer; but that one is initialized in a safe way so it doesn't have the problem. It's the new usage of the conversions_lock that puts _nl_find_msg at risk. So even though the underlying problem has existed for years, it didn't manifest, at least not right there.

So I suppose that SuSE is tracking upstream closely and you recently updated glibc ...

Oh, yeah, I'm done. Thanks for letting me poke at it.
