Subject: Embedding Ruby as a plugin (e.g. PhotoShop)

I'm trying to embed Ruby as a plugin to a program called
Animation:Master (http://www.hash.com/).  Everything compiles
and links without errors, and my plugin loads into A:M, and
my file requestor pops up for selecting which script I wish
to run through the Ruby interpreter.

After this, though, I can't seem to get Ruby to run.

If I try this:

   int myargc = 2;
   char* myargv[] = { "ruby", "c:/src/hi.rb", 0 };
   ruby_init();
   ruby_options(myargc, myargv);
   ruby_run();  // - crash

the entire application crashes on the call to ruby_run.
If, however, I try this:

   ruby_init();
   ruby_script("embedded");
   rb_load_file("c:/src/hi.rb");
   ruby_run();  // - hangs

the entire application just hangs... I have to kill it myself.

Just to test out my sanity, I built a separate executable with
the above 2 snipits, and each of them worked fine as a stand-alone
program.

I've tried linking to C:\ruby\lib\msvcrt-ruby18.lib
as well as C:\ruby\lib\msvcrt-ruby18-static.lib
and they behave the same.

Can anyone think of what I might be doing wrong?

P.S. Notice how Paint Shop Pro has a python plugin for it?
It would be cool if someone wrote a Ruby plugin for it.  Thanks.
