Sorry to be the bringer of bad news, but this seems to be still occurring in 7.10.3-rc1:
https://buildd.debian.org/status/fetch.php?pkg=haskell-vector- algorithms&arch=powerpc&ver=0.7.0.1-2&stamp=1446804253 Can you try the above patch (0001-PPC-nativeGen-fix-shift-right- arithmetic-31-bit.patch)?
I could only eye-ball the code (no 32 bit installation here), but I am pretty sure this is the only case left that triggers the panic you are seeing. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10870#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
