Bug #8364

Updated by nobu (Nobuyoshi Nakada) over 7 years ago

=begin 
 This problem was originally reported to vim-jp project.    See 
 ((<URL:https://github.com/vim-jp/issues/issues/372>)) https://github.com/vim-jp/issues/issues/372 (Japanese discussion). 

 ((<Vim|URL:http://www.vim.org/>)) Vim (http://www.vim.org/) is an text editor and it supports embedded 
 ruby interface so that we can customize Vim with Ruby.    On Mac, ruby 
 causes crash. 

 Steps to reproduce: 
   $ vim 
   :function! F() 
   :    ruby nil 
   :endfunction 
   :call F() 
   :ruby 10000.times { 'x' * 10000 } 
   Vim: Caught deadly signal ABRT 
   Vim: Finished. 

 Version is: 
   Mac OS X 10.7.5 
   ruby-2.0.0-p0 
   Vim 7.3.918 


 Maybe the following is minimum C code to reproduce crash. 

   

 ```c 
 /* rubyembed.c */ 
   
 #include <ruby.h> 

   

 void rbinit() { 
       
     int dummy_argc = 2; 
       
     char *dummy_argv[] = {"foo", "-e0"}; 
       
     RUBY_INIT_STACK; 
       
     ruby_init(); 
       
     ruby_process_options(dummy_argc, dummy_argv); 
   
 } 

   

 void rbexe(const char *src) { 
       
     int state; 
       
     rb_eval_string_protect(src, &state); 
       
     if (state) 
           
         ruby_error_print(); 
   
 } 

   

 void init() { 
       
     int eatstack[1024]; /* perhaps you need more to crash */ 
       
     rbinit(); 
   
 } 

   

 int main(int argc, char **argv) { 
       
     init(); 
       
     rbexe("10000.times { 'x' * 10000 }"); 
       
     return 0; 
   
 } 

  
 ```

 I am not sure that this is correct fix but above problem seems 
 disappeared with this.

 Or perhaps such code is not valid or something is wrong in Vim's if_ruby code?
