I haven't had time to narrow down the testcase or determine how many packages are affected yet. Some packages fail to build with the following error. I think it's related to a newer binutils, as I found a similar OCaml bug ( might be one to watch too). /tmp/ghc3974_0/ghc3974_0.s:12674:0: Error: .size expression does not evaluate to a constantThe build log attached is using ghc6. Maybe we should wait for all the libraries to be compiled with GHC 7 and then try to understand if the bug survived the compiler major version change (hoping it won't).
It did, but I reported it upstream and it was fixed (by making -fvia-c a noop). If you encounter this in the meantime (before we get a newer ghc version) then you can work around it by not using -fvia-c. Or we could backport the fix. But I suggest we just get it naturally from upstream. Thanks, Iain  http://hackage.haskell.org/trac/ghc/ticket/5050
