Subject: Embedded Ruby 1.8.7—Segmentation fault

Dear community,
I would appreciate if you could help me to solve this. I’m experimenting
with Ruby 1.8.7 embedding. Ruby has been built from sources under
Windows by VisualStudio 2008 compiler, with no errors.

Here is my C++ code:

void main()
{
  __try
    {
    RUBY_INIT_STACK;
    ruby_init();
    ruby_init_loadpath();

                ruby_incpush( "C:/ruby1.8.7/lib/ruby/site_ruby/1.8" );
                ruby_incpush(
"C:/ruby1.8.7/lib/ruby/site_ruby/1.8/i386-msvcr90" );
                ruby_incpush( "C:/ruby1.8.7/lib/ruby/site_ruby" );
                ruby_incpush( "C:/ruby1.8.7/lib/ruby/vendor_ruby/1.8" );
                ruby_incpush(
"C:/ruby1.8.7/lib/ruby/vendor_ruby/1.8/i386-msvcr90" );
                ruby_incpush( "C:/ruby1.8.7/lib/ruby/vendor_ruby" );
                ruby_incpush( "C:/ruby1.8.7/lib/ruby/1.8" );
                ruby_incpush(
"C:/ruby1.8.7/lib/ruby/1.8/i386-mswin32_90" );

    ruby_script( "embedded" );
    rb_load_file( "test.rb" );
    ruby_run();
    }
  __finally
    {
    ruby_finalize();
    }
}


Please note, it’s only an experiment, so please don’t pay much attention
on irrelevant mistakes.

This is my test.rb:

print "\n=== RUBY ===\n"

print "Hello World!"*3;

print "\n\nLoad:\n"
print $LOAD_PATH
print "\n"

require '1'
m = My.new
m.hello

print "\n=== GETTING LOCALHOST... ===\n"
require 'socket'

host = 'localhost'
port = 80
path = "/"

request = "GET #{path} HTTP/1.0\r\n\r\n"

socket = TCPSocket.open( host, port )
socket.print( request )
response = socket.read

headers, body = response.split( "\r\n\r\n", 2 )

print body



And that is 1.rb, which is located near test.rb:

class My
  def hello
    print "Hello from class My";
  end
end


The socket code actually produces segmentation fault. More precisely
it’s the “require” statement. So everything works well except the socket
part. And by commenting out all the socket-relevant code, I’ve learned
that exactly the “require” statement causes the issue.

Note, everything works great when I run the script by ruby.exe, compiled
myself!

Please help me to proceed.
Thank you.
