I mailed this scenario a month or so earlier but got no
replies. Now the problem is haunting me again and I need urgent help. Coming to the point, I have an in-house debugger integrated
in visual studio that I use to debug our game scripts. Its an embedded debugger
that uses lua hooks for debugging purposes (uses LUA_MASKLINE | LUA_MASKCALL | LUA_MASKRET). The problem
arises when I am in the middle of a debugging session (i.e. inside the hook
procedure), executing the code step by step, when a particular line of lua code
calls a C function which in turns calls lua_dofile(…) on another script
file. In such a scenario, the application crashes! The entire call stack that
is accessible to me is give in the end. I can’t seem to figure out the
problem. Can someone help me out please? Is there something that I am doing
wrong or is it a lua bug? Thanks in advance. ntdll.dll!7c901230()
