emerge-info.txt

Just hit this on one of our servers, but the mail is stopped temporarily so I can't troubleshoot right now.

Error:

  ghc-stage1: panic! (the 'impossible' happened)
    (GHC version 7.8.4 for x86_64-unknown-linux):
  	Ix{Int}.index: Index (58925215) out of range ((0,5250))

  Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

  compiler/ghc.mk:646: recipe for target 'compiler/stage2/build/IOEnv.o' failed

Comment 2 Sergei Trofimovich (RETIRED) gentoo-dev 2015-01-11 19:04:16 UTC 
I have hardened toolchain only in amd64 chroot. ghc-7.8.4
seems to build fine here.

Does bug appear for you exactly the same if you try to
build ghc one more time? I wonder if it's a toolchain
version breaking things here or a MAKEOPTS.
Comment 3 Michael Orlitzky gentoo-dev 2015-01-11 19:25:20 UTC 
I use hardened everywhere, so that's not the (only) issue. My second attempt generated:

  ghc-stage1: out of memory
  compiler/ghc.mk:646: recipe for target 'compiler/stage2/build/MkCore.o' failed

I'm trying it with -j8 now.
Comment 4 Michael Orlitzky gentoo-dev 2015-01-11 19:40:17 UTC 
With -j8:

  ghc-stage1: panic! (the 'impossible' happened)
    (GHC version 7.8.4 for x86_64-unknown-linux):
          Ix{Int}.index: Index (3539992580) out of range ((0,5250))

Trying -j1 just to be sure...
Comment 5 Michael Orlitzky gentoo-dev 2015-01-11 19:42:03 UTC 
That last error was in a different place by the way:

  compiler/ghc.mk:646: recipe for target 'compiler/stage2/build/X86/RegInfo.o' failed
Comment 6 Michael Orlitzky gentoo-dev 2015-01-11 21:27:30 UTC 
Somehow, it survives with MAKEOPTS="-j1".
Comment 7 Michael Orlitzky gentoo-dev 2015-10-13 14:57:53 UTC 
Life goes on =)
