 This ticket is a follow-up to the [http://lists.gnu.org/archive/html
 /chicken-users/2010-12/msg00074.html email thread] I posted about this
 issue.

 I'm running chicken 2bb09388cff32b7ecb49f39df0692e2d4db7a0bf (silly link
 case problems, tiring) from the experimental branch.  I'm on OpenBSD 4.8
 running in a VMWare virtual machine.

 This bug refers to the [http://wiki.call-cc.org/eggref/4/genturfahi
 genturfa'i egg].

 For this bug, please check out r21827 from the egg repository, apply the
 patches attached to this e-mail, and build the egg:

 {{{
 svn co -r21827 https://code.call-cc.org/svn/chicken-
 eggs/release/4/genturfahi/trunk
 cd trunk
 patch -p1 < patch-conf    # enable full debugging
 patch -p1 < patch-memoize # the do-nothing memoizer
 chicken-install -s
 }}}

 Run the genturfahi command-line program after installing the egg:

 {{{
 $ genturfahi

 Error: stack overflow

         Call history:

         nunjavni.scm:176: nunjavni-*
         nunjavni.scm:140: venunjmina-rodanunvalsi
         morji.scm:47: hash-table-exists?
         bootstrap.scm:369: genturfahi#morji-nunjavni-valsi
         morji.scm:47: hash-table-exists?
         morji.scm:48: hash-table-set!
         bootstrap.scm:366: genturfahi#morji-nunjavni-je
         nunjavni.scm:245: venunjmina-rodanunvalsi
         nunjavni.scm:247: filter
         morji.scm:47: hash-table-exists?                <--
 }}}

 This error is happening while genturfahi is initializing, the most outward
 relevant line being bootstrap.scm:366.

 If you comment out morji.scm:47 and morji.scm:48, run chicken-install -s,
 the program will run without producing any output (which is expected.)

 I would expect to be able to leave morji.scm:47 and morji.scm:48
 uncommented in the code and run genturfahi without generating a stack
 overflow error.

 This problem *also* exists when running the code from csi, without
 compiling it:

 {{{
 # This command may give an error if csi is an alias that includes
 # command-line arguments, as in: alias csi='csi -quiet'.  Run csi
 # without command-line arguments.
 #
 $ csi chicken-csi.scm

 Error: stack overflow

         Call history:

         <eval>    [morji-nunjavni] (not (hash-table-exists? morji sumti))
         <eval>    [morji-nunjavni] (hash-table-exists? morji sumti)
         <eval>    [morji-nunjavni] (hash-table-set! morji sumti javni)
         <eval>    [morji-nunjavni] (apply nunjavni sumti)
         <eval>    [nunjavni-+] (##sys#get-keyword (quote cmene:) tmp268)
         <eval>    [nunjavni-+] (nunjavni-* javni cmene: cmene)
         <eval>    [nunjavni-*] (##sys#get-keyword (quote cmene:) tmp241)
         <eval>    [nunjavni-*] (venunjmina-rodanunvalsi cmene)
         <eval>    [morji-nunjavni] (not (hash-table-exists? morji sumti))
         <eval>    [morji-nunjavni] (hash-table-exists? morji sumti)
 <--
 }}}

 This error also goes away if you comment out morji.scm:47 and
 morji.scm:48.
