Summary: panic! ...  forkM Declaration for tables{v}

Initial Comment:
Got this while trying to build the examples code in 
HSsql. I am obviously having problems with locations of 
interface files. 

The complete verbage is:

Mark@mark-
xsd45hrekw /dosC/Software/haskell/hsql14_src/HSQL/e
xamples
$ ghc -package hsql Queries.hs
c:/Software/haskell/ghc-
6.4.0/imports/Database/HSQL.hi :
  Can't find interface-file declaration for 
Database.HSQL.Types.Connection
    Probable cause: bug in .hi-boot file, or 
inconsistent .hi file
    Use -ddump-if-trace to get an idea of which file 
caused the error
ghc.exe: panic! (the `impossible' happened, GHC 
version 6.4):
        forkM Declaration for tables{v}

Please report it as a compiler bug to glasgow-haskell-
bugs@xxxxxxxxxxx,
or http://sourceforge.net/projects/ghc/.

Bummer, how do you attach files to this page? Find my
references at
http://tac.ki.iif.hu/attach.tgz instead.

OK, let me try.  First of all I applied the attached patch, then
./configure --prefix=/home/wferi/wash
make depend
make all
make install
which bailed out when tried to update the system
package.conf since I wasn't root.  Nevermind, Wash isn't
compatible with GHC 6.4 anyways, so I hacked together a user
package.conf via ghc_pkg (attached).
Then I typed in the first example from the Wash manual
(attached) and tried to compile it.  I couldn't find a trace
of extra_ghc_opts or similar, so had to provide those
options on the command line.  Hope I didn't forget anything.
 FreeBSD 5.3-STABLE, btw.

Can someone give complete instructions for how to reproduce 
this bug?  E.g. I'm busy compiling WASH, but it looks as if 
you have to install it and compile something else too...

Step by step repro instructions would be v helpful.

I've got similar output when trying to compile WashNGo 2.3.1:

$ ghc -package WASH --make Main -F -pgmF
/home/wferi/wash/bin/wash2hs
Chasing modules from: Main
Compiling Main             ( Main.hs, Main.o )
/home/wferi/wash/lib/WASH-CGI-1.4.37/ghc-6-4/import/CGIInternals.hi
:
  Could not find module `HTMLMonadBase':
    it is not a module in the current program, or in any
known package.
ghc-6.4: panic! (the `impossible' happened, GHC version 6.4):
        forkM Declaration for ask{v}

Please report it as a compiler bug to
glasgow-haskell-bugs@xxxxxxxxxxx,
or http://sourceforge.net/projects/ghc/.

I experience this under FreeBSD with GHC compiled from ports.
