hi I need to integrate some scripting engine into my app (it is native x64 windows app) on 32bit target all is fine, angel script works as charm, but when compilled as x64 target (using vc2008 with sp1) there is a crash at asCContext::Release (the heap manager tells that block is corrupted) Is angel script usable in x64 environment ? or are there any known issues (expect that only GENERIC calls allowed, not the native ones) callstack of the crash: RayCaster.exe!_CrtIsValidHeapPointer(const void * pUserData=0x000000000dc6d4b0) Line 2103 C++ RayCaster.exe!_free_dbg_nolock(void * pUserData=0x000000000dc6d4b0, int nBlockUse=1) Line 1317 + 0xa bytes C++ RayCaster.exe!_free_dbg(void * pUserData=0x000000000dc6d4b0, int nBlockUse=1) Line 1258 + 0xe bytes C++ RayCaster.exe!free(void * pUserData=0x000000000dc6d4b0) Line 50 C++ > RayCaster.exe!asCContext::Release() Line 200 C++ RayCaster.exe!asCModule::CallInit() Line 193 C++ RayCaster.exe!asCModule::Build() Line 152 C++ RayCaster.exe!asCScriptEngine::Build(const char * module=0x0000000000000000) Line 499 + 0x10 bytes C++ RayCaster.exe!SceneCreate() Line 151 + 0x19 bytes C++ RayCaster.exe!wWinMain(HINSTANCE__ * hInstance=0x000000013f3d0000, HINSTANCE__ * hPrevInstance=0x0000000000000000, wchar_t * lpCmdLine=0x00000000003e49cc, int nCmdShow=1) Line 110 C++ RayCaster.exe!__tmainCRTStartup() Line 263 + 0x42 bytes C RayCaster.exe!wWinMainCRTStartup() Line 182 C BTW. The examples provided with AS crash in that same place when compilled as x64 apps, so this is not my app specific. Meybe the vc2008 have to do something with this ? (but sp1 fixed most of the compiller errors IMHO)

Ok, so i take a closer look at it tomorow :)

... ok, i could not sleep :)
so i'v debugged as a little and it turns out that 'AS_64BIT_PTR' was not defined
in as_config.h <lol>
vc2008 x64 target do not define __LP64__ nor __amd64__, soo AS_64BIT_PTR must be added as /D command line option or defined explicite in config

now all works like a charm :)
... and this heap corruption was from critical section that is defined as 6 bytes for 32bit and 10 bytes for x64 (btw. its dangerous to 'redeclare' CRITICAL_SECTION in AS, it really should be taken from windows.h)

For x86-64 MSVC defines the _M_X64 macro.
