Re: Haskell Platform 2013.2 Proposal Status

Did anyone spend time trying to identify / bisect when the bug was fixed between 7.6.2 and ghc head? (and backport the logic to resolve it) would be a shame to not have the next haskell platform use 7.6 ... On Fri, Apr 12, 2013 at 7:12 AM, Roman Cheplyaka wrote:

Hi,

I just spoiled my day by http://hackage.haskell.org/trac/ghc/ticket/7748 with ghc-7.6.2 in our large project:

hets: <<loop>>

hets works fine with ghc-7.6.1 (and older versions). I haven't located the error yet, though.

Yet, I therefore conclude, GHC 7.6.2 ist not suited for the official HP.

I don't think this is enough data to make such a conclusion. GHC 7.6.2 may have fixes for bugs that are present in GHC 7.6.1, for example.

So we need to compare the fixed bugs versus regressions in 7.6.2 to make the choice.

(OTOH, the looping bug is a nasty one, if you ask me, and is difficult to debug.)
