The following reply was made to PR threads/83914; it has been noted by GNATS. From: "Andrey Sverdlichenko" <blaze@ruddy.ru> To: bug-followup@freebsd.org, phk@critter.freebsd.dk Cc: Subject: Re: threads/83914: [libc] popen() doesn't work in static threaded programs. Date: Fri, 13 Jul 2007 13:10:54 +0400 It's linking issue. In dynamically linked executable vfork() mapped to threaded library by weak_reference. In statically linked binary popen() calls vfork() from libc.a, but later calls _execve() from libpthread.a since it's not weak symbol.
