In the interest of bit-wise exactly reproducible compilation (#4012), the basename of the temporary file no longer contains random information (it used to ontain the process id). This is ok, as the temporary directory used contains the pid (see getTempDir). This patch has been applied to the Debian package (version 7.10.1-5) and allowed a fully bit-wise reproducible build: https://reproducible.debian.net/rb-pkg/experimental/amd64/ghc.html Reviewed By: austin, rwbarton Differential Revision: https://phabricator.haskell.org/D910 GHC Trac Issues: #4012 }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/4012#comment:89> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
