Hi,

I try to embed a Ruby interpreter into an application through a shared  
library. This application can call more than one time Ruby interpreter.  
In the attached testcase, first call works as expected but next calls  
create a segmentation fault.

Any idea of what is wrong in my code or is it really a Ruby bug?

I use Ruby 1.8.7-p248 and have the same behavior (ie segfault) with Ruby  
1.9.1.

Thanks for your consideration,  
David
