Θέμα: Re: Offset and out of bounds
You are looking at why it is called, right? In gdb you can use the *up *command
to look up the call stack to see what called something.
That function, btw, will get called by anything that needs to deserialize
agtype to agtype_value, even multiple times within a single agtype, due to
nested structures.
