ghc-6.6 under solaris

I've created ghc-6.6 under solaris. This did only work with SplitObj=No in mk/build.mk. (There was an early split error, that I could reproduce.) When trying out this compiler, I got the following error (that I only post for the record): Cheers Christian [410 of 642] Compiling Proofs.HideTheoremShift ( Proofs/HideTheoremShift.hs, Proofs/HideTheoremShift.o ) ghc-6.6: panic! (the 'impossible' happened) (GHC version 6.6 for sparc-sun-solaris2): lookupDeprec main:GUI.ConsoleUtils.listBox{v r36Wf} Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug gmake: *** [hets] Error 1
