Re: ANNOUNCE: GHC 7.4.1 Release Candidate 2

I too was seeing this with RC1, but I haven't tried RC2. Looking at the commits on the 7.4 branch, I don't see anything that would have likely affected/fixed it, so I speculate I'll see the same thing with RC2. I'll try tonight and report back. I will note that manually built copies of HEAD work just dandy. I do wonder if it's a problem with the binary distribution itself, as opposed to some bug fix that didn't get merged into 7.4. I wonder if I built my own copy and binary-dist of 7.4 if GHCi would segfault or not - this would indicate it being a problem with the binary distribution if it doesn't (which sucks, as it means you have to compile it yourself.) Ian, can I ask what the procedure would be to check out the 7.4 branch of GHC and all the associated libraries to try this out? I'm not familiar with all the `sync-all`-fu, but I speculate it's what'll do it. :) On Fri, Jan 27, 2012 at 10:57 PM, Evan Laforge wrote:

Unfortunately ghci still segfaults for me most times (the previous release candidate did too).  Anyone else seeing this?  What should I do to troubleshoot?

OS X 10.6.8, using GHC-7.4.0.20120126-x86_64.pkg

I'll try GHC-7.4.0.20120126-i386.pkg in a bit, but I probably do need the 64 bit version, previously I had to hassle around with the 32bit version because it didn't want to link with all the other 64 bit compiled code.

Also, I notice that the ghc, ghci, ghc-pkg, and haddock links are all versioned, but not hsc2hs.  hsc2hs is also highly dependent on the ghc version so it should be versioned too!  I suppose this is for the mac package maintainer (Mark M, that's you, right?).  What I mean by versioned is that the other binaries have a ghc and then a ghc-$version link, so I can switch ghc versions by running a little shell script.  But for hsc2hs I have to create the hsc2h-$version link first.  Not a big deal, just a minor quibble.

We are pleased to announce the first release candidate for GHC 7.4.1:

   http://www.haskell.org/ghc/dist/7.4.1-rc2/

This includes the source tarball, installers for OS X and Windows, and bindists for amd64/Linux, i386/Linux, amd64/FreeBSD and i386/FreeBSD.

Please test as much as possible; bugs are much cheaper if we find them before the release!

We expect this to be the last release candidate, with the final release in approximately 1 week's time.

Thanks Ian, on behalf of the GHC team
