DetailsDescription:
When launching cjdns, it fails with "INFO Pipe.c:78 Failed to write to pipe [/var/run/cjdns_pipe_client-core-zfr3bf3m5mdm1tdc7mg1cn7qz3nw1j] [invalid argument]". This also occurs when tests are ran, which happens automatically after compilation. This issue seems to be glibc-related, as it started happening after an upgrade to glibc 2.26, and 'drathir' on IRC (EFnet) has experienced the same thing. (If it is a glibc bug, sorry for filing it here.) Additional info: * package version(s): 20-1 *and* latest git commit * config and/or log files etc.: see attachment for a full log of the test run. The error happens at line 7655. Steps to reproduce: 1. Install cjdns (or clone the upstream version from https://github.com/cjdelisle/cjdns) 2. Run `cjdroute`, or build and test it using `./do`.

The bug in question was caused by sysconf(3) returning -1 without setting errno (seems to be new behavior AFAIK), which made a writev(3) call fail in the libuv fork (upstream libuv handles this, but incorrectly), causing CJDNS to fail to create a pipe, making it unable to launch. See https://github.com/cjdelisle/cjdns/pull/1107 and https://github.com/libuv/libuv/pull/1539 .
Again, sorry for causing noise.
this downgrade work for me:
$ pacaur -S downgrade
$ downgrade glibc binutils
check
glibc-2.25-7
binutils-2.28.0-4
add to /etc/pacman.conf
IgnorePkg = glibc binutils
reboot
