Hi, I am integrating Ruby with C++ on MS Windows 7 (using Visual Studio). My code crashes when ruby_errInfo is used to get an error message after rb_load_protect fails. By the way, the script I am trying to load is a simple "hello world" function and there is nothing wrong in it. But still, rb_load_protect fails and I am unable to get details from ruby_errinfo. Below is the relevant code snippet: ruby_incpush (myFolder); ruby_init_loadpath(); ruby_set_argv (argc, argv); ruby_script (myRubyFile); rb_load_protect (rb_str_new2(myRubyFile, 0, &status); if (status != 0) { VALUE info = ruby_errinfo; VALUE str = rb_obj_as_string(info); // <-- crashes here : } The code crashes when info is converted into str via rb_obj_as_string(). Further investigation tells me that it's this call inside rb_obj_as_string() which fails: str = rb_funcall(obj, rb_intern("to_s"), 0); Any ideas what's going on? Or how I can troubleshoot? -- Posted via http://www.ruby-forum.com/.
