Interesting. Thanks for the report, I'm trying to narrow down the issue now. Can you describe the circumstances that cause this? Does it happen every time or occasionally? Are you calling Duktape.create from multiple threads concurrently?

[NitroXenon]

Yes I was calling it from multiple threads. My app just threw this error and crashed after half of the JavaScript was being evaluated.

[swankjesse]

Are you using one Duktape instance per thread?

[NitroXenon]

Yes

This should be fixed by #67. Please re-open if not.

Alright thanks. :D
