Thank you for so fast fix!

@haukot ,

Thank you very much for opening this issue!

I guess it's because there is direct Ruby C API function call instead of RubyCaller call

Yes, you're correct.

However, RubyCaller wouldn't help to fix this issue, because the issue is in the RubyCaller implementation.

The best solution is to redesign the RubyCaller implementation so it always protects against exceptions, so it will wrap the code and protect it at this point.

At the moment, RubyCaller only protects against exceptions if the GVL state needs to be updated when entering Ruby code, not when entering C code.

I wrote a fix in the 0.5.0 version branch, I will see if I can back port it to the 0.4.x version branch.

I released version 0.4.17 which should solve the issue.

Again, thank you very much for detecting this issue 🙏🏻
