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.

Thanks for your consideration,
David

Well, I idenfitied that this bug is due to an unexpected behavior with dlclose().

My question is : why require 'fileutils' for instance do not allow dlclose() to close immediatly libruby.so and waits for end of program execution? Is there a way to unload libraries loaded by require?

Regards,
David

That's because we don't need.

Is there a way to unload libraries loaded by require?

You can know loaded library files by get_loaded_features().
