Ah, it's getting EAGAIN from fds created from prior pipe() calls. The other sides look like they were DUP2'd to fds 0&1, I'm guessing for a fork/exec().
Well, that isn't a big surprise - it's the way you would expect to get EAGAIN. So ... evidently the GHC runtime is broken somehow on OpenSolaris? I personally have no idea what's going on there, but while we're waiting for someone with a clue, here are a couple more random things to try: Have you compiled and run separately? instead of
runghc Setup.hs configure
ghc --make Setup Setup configure It shouldn't make any difference on its own, but then you can try options on the compile, like "ghc -threaded", and runtime flags like "Setup +RTS -V0 -RTS" I suggest that because it cuts down on signal interrupts from the runtime, and your symptoms suggest a signal interrupt.
