How to debug AV on garbage collection in luabind::object_rep destruction?

Alexander Gladysh
Hi, all!

Luabind b7, Lua 5.0.2, VC8.

I've found that my application crushes in depths of Luabind with
Access Violation on some circumstances when Lua garbage collection is
invoked either manually or automatically. Is there any hints to help
me to find which of my Luabind-bound objects does that bad thing? Call
stack follows.

Starting from lua_reference::~lua_reference() state (0x03bdc5a0) seems
to be corrupt (almost all members are set to 0xfeeefeee).

Note that I'm using some number of nested coroutines in my
application, this may be (or may be not) related to the source of the
problem.

Thanks in advance,
Alexander.
