When I try using AS_DEBUG on Win x64 version, it crashes on some my scripts.

I was found, that crash caused in as_bytecode.cpp in DebugOutput, on lines

asCScriptFunction *f = engine->scriptFunctions[instr->wArg[0]];

instr->wArg[0] is short, and become negative on big functions number, and converting it to asUINT index created big number out of bound array. In my case function number was 0x81d8. Replacing line by

asCScriptFunction *f = engine->scriptFunctions[(unsigned short)instr->wArg[0]];

is solved problem.

It is Urho3D game engine. Recently in it was created autogenerator of AngelScript bindings for it object model, and function count was doubled ?

For example, last auto-header for IDE autocomplete - https://raw.githubusercontent.com/urho3d/Urho3D/master/Docs/AngelScriptAPI.h
