MSAOpenCL assertion fail

Hello, I’m trying to compile Memo’s OpenCl example, this one
/MSAOpenCL/examples/openFrameworks/MSAOpenCL/exampleMSAOpenCL—images

I got the other 2 (hello world and particles) easily enough, but this one launches only to receive a SIGABRT signal…

this is what i get:
Assertion failed: (err != CL_INVALID_VALUE), function initFromTexture, file /Users/GeckoDrive/Desktop/of_preRelease_v0061_osx_FAT/apps/addonsExamples/openCLVideoExp/…/…/…/addons/MSAOpenCL/src/MSAOpenCLImage.cpp, line 119.

and this is the line it points to, on the MSAOpenCLImage.cpp file

  
void OpenCLImage::initFromTexture(ofTexture &tex,  
									  cl_mem_flags memFlags,  
									  int mipLevel)  
	{  
		  
		ofLog(OF_LOG_VERBOSE, "OpenCLImage::initFromTexture");  
		  
		init(tex.getWidth(), tex.getHeight(), 1);  
		  
		cl_int err;  
		if(clMemObject) clReleaseMemObject(clMemObject);  
		  
		clMemObject = clCreateFromGLTexture2D(pOpenCL->getContext(), memFlags, tex.getTextureData().textureTarget, mipLevel, tex.getTextureData().textureID, &err);  
		assert(err != CL_INVALID_CONTEXT);  
		assert(err != CL_INVALID_VALUE);  //line 119  
		//!	assert(err != CL_INVALID_MIPLEVEL);  
		assert(err != CL_INVALID_GL_OBJECT);  
		assert(err != CL_INVALID_IMAGE_FORMAT_DESCRIPTOR);  
		assert(err != CL_OUT_OF_HOST_MEMORY);  
		assert(err == CL_SUCCESS);  
		assert(clMemObject);  
		  
		texture = &tex;  
	}  
	  
  

if i comment the 119th line, it just points another assertion down the line…

I have no idea what is happening, could someone please point me in the right direction?

thanks

all the best
