Daniel, maybe you can send a followup to the following ? http://www.freebsd.org/cgi/query-pr.cgi?pr=110655 Given that 32-bit libthr also doesn't work on 64-bit kernel, the only option is to map thread libs to libc_r via libmap32.conf. BTW, next time there is a poll about retiring libc_r please count me against for precisely this reason. -- Andriy Gapon
