This bug will track the issue with respect to testsuite validation failure in particular. My attempt at fixing this was Phab:D1599 but sadly this doesn't appear to be sufficient. In particular it appears that bindist preparation strips binaryies. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11205#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

If you find that it does, then that is a bug, and I'd like to know which file in `bindistprep/` is stripped. validate also tries to **install** the binary distribution, by running 'make install'. Since it doesn't run 'make install-strip', it won't strip the installed executables (ghc, ghc-pkg, haddock, etc.). Whether it strips libraries (.a and .so files) should depend on the setting of STRIP_CMD. There could be a bug here, maybe in Cabal. It would help to know which file in `bindisttest/` is stripped after running `./validate`, when `STRIP_CMD=:`. Make sure you're using HEAD, not ghc-7.10. Stripping was broken before (see ticket:1851#comment:16). ticket:10601#comment:4 is also relevant. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11205#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Hi Thomie; I am quite certain I am on `master`. In particular, with
b02838405b00bcdeebb44da0a7a9562cd7fda66b with Phab:D1599 I am seeing this
