However, I've tried integrating the new vector/primitive versions released into the GHC build (after patching up the DPH libs), but I get Core lint errors:
any idea what's going on here?
Hm, #8138? Richard marked that as closed, though.
You didn't try to update the version of vector in the GHC build, did you?
Well, of course I did :-)
but afaics the error occurs already when trying to compile the new 'primitive' by itself...
But you can easily reproduce w/o replacing the 'primitive' used for building GHC HEAD, but simply by trying to build the relased primitive-0.5.1.0 package with GHC HEAD via cabal:
cabal update cabal install --ghc-option=-dcore-lint primitive-0.5.1.0
Looks like #7643. Here's my work-around: https://github.com/mainland/primitive/commit/21fd4d055a26552919d06fbf7433f72... Note that DPH is tied to the old version of vector, so updating vector will not work. I have patches to DPH to get it to compile with the new version of vector, but the DPH folks have plans to re-do the way vectorization is done, so it's probably not worth trying to get my patches included.
