Problem saving/loading bytecodes (angelscript bug?)

Hi there! I'm trying to save/load to/from bytecode file. But if i use arrays in the script, the application crashes with an access violation when loading the binary file: // NEXT: Must go through the bytecode and set the correct objecttype pointer where used int asCRestore::Restore() { // Before starting the load, make sure that // any existing resources have been freed module->Reset(); unsigned long i, count; asCScriptFunction* func; asCProperty* prop; asCString *cstr; // structTypes[] READ_NUM(count); module->classTypes.Allocate(count, 0); for( i = 0; i < count; ++i ) { asCObjectType *ot = NEW(asCObjectType)(engine); ReadObjectTypeDeclaration(ot); engine->classTypes.PushLast(ot); module->classTypes.PushLast(ot); ot->refCount++; } // usedTypes[] READ_NUM(count); module->usedTypes.Allocate(count, 0); for( i = 0; i < count; ++i ) { asCObjectType *ot = ReadObjectType(); module->usedTypes.PushLast(ot); ot->refCount++; } . . . } In the last line (ot->refCount++) ot is NULL, so there i have the access violation. Here's the script i've used: Sprite spr; float[] f(5); bool Initialize() { if (!spr.Load("data/graphics/roxy.spr")) return false; spr.SetFrame(10); spr.SetPos(20,20); return true; } void Update(float dt) { spr.Update(dt); } void Draw() { spr.Draw(); } If I comment the float[] f(5); line, the problem dissapear. Is it something i'm doing wrong when registering the arrays? Here is how I registered the floats array: if (ScriptMgr::RegisterObjectType("float[]", sizeof(vector<float>), asOBJ_CLASS_CDA) < 0) return false; if (ScriptMgr::RegisterObjectBehaviour("float[]", asBEHAVE_CONSTRUCT, "void f()", asFUNCTIONPR(ConstructFloatArray, (vector<float> *), void), asCALL_CDECL_OBJLAST) < 0) return false; if (ScriptMgr::RegisterObjectBehaviour("float[]", asBEHAVE_CONSTRUCT, "void f(int)", asFUNCTIONPR(ConstructFloatArray, (int, vector<float> *), void), asCALL_CDECL_OBJLAST) < 0) return false; if (ScriptMgr::RegisterObjectBehaviour("float[]", asBEHAVE_DESTRUCT, "void f()", asFUNCTION(DestructFloatArray), asCALL_CDECL_OBJLAST) < 0) return false; if (ScriptMgr::RegisterObjectBehaviour("float[]", asBEHAVE_ASSIGNMENT, "float[] &f(float[]&in)", asMETHODPR(vector<float>, operator=, (const std::vector<float> &), vector<float>&), asCALL_THISCALL) < 0) return false; if (ScriptMgr::RegisterObjectBehaviour("float[]", asBEHAVE_INDEX, "float &f(int)", asMETHODPR(vector<float>, operator[], (vector<float>::size_type), float &), asCALL_THISCALL) < 0) return false; if (ScriptMgr::RegisterObjectMethod("float[]", "int length()", asMETHOD(vector<float>, size), asCALL_THISCALL) < 0) return false; Thanks a lot!

That's great to hear. Thanks for confirming it.

I'm having problems again with the final version of AngelScript 2.8.1 when Loading/Saving bytecode without any changes in the scripts.

Did you change anything from the last revision to this in this section of the library?

Oops, sorry... my fault. It was a compiling problem. Fixed! ;)
