Post Cannot push twice in on_extract (yo_cupdate expected oxy...)

I recently wanted to implement an on_extract method for an opaque object. When I push more than one value one the stack, on_extract fails with
ERROR (*main*) (BUG) yo_cupdate expected oxy_context
In addition, the return value seems to be not the last value pushed, but the one before.

I attach a minimal example where one can see that on_eval works as expected but on_extract fails:
File comment: Minimal example
foo.tgz [1.5 KiB]
Downloaded 174 times
The two function are identical (except for their signature of course):
void foo_extract(void * obj, char * member)

The failure is the same whatever I push (nil, longs, strings etc.).

For my purpose I found a simple workaround (I can drop each item before I push the next one) but I thought you would be interested.

Kind regards, Thibaut.

Commit a66b1c1 at fixes this.

Thank you very much. This was a serious stack mis-positioning error.
