I thought that’s what "merged in ..." meant... but now I see that you did not merge the amd64 support, but rather some alias handling. Marking this as merge in case this is just an oversight, and there was a plan to merge the AMD64 support in 7.8.4. Just close it again if that was not the intention. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/7942#comment:57> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

I always get {{{ Hpc failure: module mismatch with .tix/.mix file hash number (perhaps remove foo.tix file?) }}} With 7.4.1, it segfaults about 10% of the times when I add `module Main where` to the top of `foo.hs`. To reproduce, save `foo.hs` and `Bar.hs` in subdirectory `original`. Then run the following script. {{{ set -x GHC=ghc rm foo* Bar* cp original/*.hs . $GHC -O -fhpc foo.hs ./foo cat foo.tix mv Bar.hs Bar.hs.orig sed -e 's/import/-- import/' -i.bak foo.hs rm -f *.hi *.o $GHC -O -fhpc foo.hs ./foo }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/7033#comment:3> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
