AngelScript wiith JIT: calling function of the POD type corrputs stack about angelscript-jit-compiler HOT 2 CLOSED

Thanks for the detailed bug report. This looks like it's a problem in the implementation of asCALL_CDECL_OBJLAST when there are no more registers available for arguments and the object pointer needs to be passed on the stack.

I don't have an appropriate test case to try it on right now, but could you try adding to as_jit.cpp

    if(pos == OP_Last) {
        if(!cpu.isIntArg64Register(intCount, a))
            stackBytes += cpu.pushSize();
    }

on line 3590 of as_jit.cpp, like this:

@@ -3588,6 +3588,11 @@ void SystemCall::call_64conv(asSSystemFunctionInterface* func,
        }
    }

+   if(pos == OP_Last) {
+       if(!cpu.isIntArg64Register(intCount, a))
+           stackBytes += cpu.pushSize();
+   }
+
    --i; --a; --intCount; --floatCount;
    cpu.call_cdecl_prep(stackBytes);

That should add the object pointer to the amount of stack bytes to be popped after the call.

Thank you for the fast answer!
I modified the code an now it calls the function properly.
