Possible cause:

These problems are happening because the duktape library calls setjmp and longjmp. When calling C code from Go, you can only use setjmp/longjmp within a single C call that does not make any intervening Go calls. Specifically, the call to ctx.RequireNumber is failing and trying to call longjmp to a setjmp that occurred before calling back into Go to invoke func. That can't work. The longjmp is skipping over the intervening Go code.

I think the status right now is that you can use duktape from Go as long as you are careful to not cause any errors. I recommend modifying the duktape code to crash on error rather than calling longjmp.

I'm going to close this issue because I don't think there is anything we can do to fix it.
