Hi everybody,

I’m writing an application, which will cooperate with ruby files. So I  
must use Ruby API (call ruby functions).

I’m using OpenMP to parallelize my program, but when I use more threads,  
program terminates with ‘segmentation fault’. I cannot use any Ruby  
function, because of this. Even when I identificate region as #critical,  
it’s ‘segfault’.

I there any way how to solve this problem?

Thank you
