[jhc] ./src/E/FromHs.hs:(869, 4)-(871, 30): Irrefutable pattern failed for pattern (p : ps)

Hi John, I'm getting the following error now: Compiling... [ 1 of 18] Jhc.AltIO ./src/E/FromHs.hs:(869,4)-(871,30): Irrefutable pattern failed for pattern (p : ps) which is the irrefutable pattern in tinyHeads. Unfortunately, I'm still pretty clueless about debugging jhc itself. I'm not sure what this function is doing, or how to figure out which code it's working on... :( P.S. You should be able to reproduce this using a darcs get http://abridgegame.org/concurrency, and trying to build jhc/Prelude.hs. -- David Roundy
