I think you should file a bug report with a test case on GHC.
I am willing to work on this, but I thought I'd go fishing for some advice first. My program uses: forkIO, STM, and FFI.
I've seen something like this, using only forkIO, so I'd start looking there. I was trying to create a reduced test case, but haven't reported a bug yet.
I think that "heap exhausted" sometimes gets reported as "evacuate: strange closure", (cf. http://hackage.haskell.org/trac/ghc/ticket/5085 ) and yieldCapability() might be another instance.
Thank you, we just had this message, and I had no idea what it was. Erik
