panic while building darcs with profiling
Building the most recent darcs with profiling causes a panic. I've attached a tarball with the code as it is at the moment (in case the repository moves on and hides the panic). The panic message follows:
[175 of 180] Compiling Darcs.Commands.WhatsNew ( src/Darcs/Commands/WhatsNew.hs, dist/build/Darcs/Commands/WhatsNew.p_o )
ghc: panic! (the 'impossible' happened)
(GHC version 7.3.20111114 for x86_64-unknown-linux):
