This command will make mcrypt crash. I guess if older versions of mcrypt work well? (didn't find an easy way to downgrade mcrypt so I'm leaving it) echo abcde | mcrypt -q -k xyz | mcrypt -dq -k xyz
0) It seems to work fine here: $ echo abcde | mcrypt -q -k xyz | mcrypt -dq -k xyz abcde $ 1) Please post your `emerge --info' output in a comment. 2) Please post the output of that command in a comment or attachment.
Tested with livedvd-x86-amd64-32ul-2012.1.iso from live.

I guess it is a mcrypt issue originally. See more systems affected, but it think it is a specific hardware that triggers the issue: http://cygwin.com/ml/cygwin/2012-07/msg00322.html http://www.freebsd.org/cgi/query-pr.cgi?pr=169986
Fixed in mcrypt-2.6.8-r2. This case anyway, code is at poor quality.
