ghc crash

[Vladimir Zykov]

Hello GHC hackers,

  I'm  rather  new  to  Haskell  but looks like I found a bug. The bug
occurs  when I try to build SYB3 package (which is necessary for HAIFA
package). I downloaded SYB3 from http://www.dcs.shef.ac.uk/~u1sf/darcs
but  it  appears  to  be  dead  now, so I attach the SYB3 archive with
the sources.

  I  have  GHC  6.4  on Windows 2000 and I did the following steps for
building SYB3:
runhaskell.exe Setup.lhs configure --ghc
runhaskell.exe Setup.lhs build

  During  building  of  Data/Generics2/Instances.hs  ghc  does  access
violation  and  the  whole  process terminates. I discovered that this
problem arises from line #506 in Instances.hs (`$(deriveTypeable [''DataType])`).
If I build without that line (and following `instance Sat (ctx DataType)`)
then everything goes fine.

So, can you help me with this?
