And any additional information you may have on this would be appreciated. trapni@gentoo.org 2004-12-18 07:41:02 0000 interesting, yeah, but able to fix? well.... I gonna take a closer look tonight on it, too... thx ;) trapni@gentoo.org 2004-12-18 07:41:49 0000 ah, btw, you can workaround this by remerging glibc without nptlonly useflag! - so much for now, cya ;) griffon26@gentoo.org 2004-12-19 10:38:44 0000 I added valgrind-2.2.0-r1 that includes a fix. If it doesn't fix the problem, please reopen this bug. Thanks for reporting the problem. pedratan@gmail.com 2004-12-19 12:51:17 0000 Excellent.
