Subject: Ruby 1.9 "exception reentered"

Hi,

I've made a module that embeds a Ruby interpreter into S-Lang
(http://www.cheesit.com/downloads/slang/slruby.html). The module
worked OK until Ruby 1.9 revision 15996 came out:

r15996 | nobu | 2008-04-14 05:52:27 +0200 (ma, 14 apr 2008) | 2 lines

* gc.c (Init_stack): use ruby_init_stack.  [ruby-dev:34350]

Now I get this error:

slsh> require("slruby");
Ruby error: fatal: exception reentered
Traceback: rb_load_file

slruby.sl imports the module (it's dynamically loaded) and then tries
to load itself as a Ruby file using the S-Lang function
rb_load_file(), which calls rb_load_protect().  If I first import it
and then require slruby.sl, it works sometimes:
slsh> import("ruby");
slsh> require("slruby");
slsh>

Can someone explain what causes this error?
