glBlitFramebuffer crash with msaa depth -> msaa depth blit on Radeon HD 4800

[eodabash]

The following code crashes on a Radeon HD 4800 (Win7 64-bit, latest drivers)

	GLuint fbo1 = 0;	
 
	// setup FBO 1
	{		
		glGenFramebuffers(1, &fbo1);
		glBindFramebuffer(GL_FRAMEBUFFER, fbo1);
 
		GLuint rb1 = 0;
		glGenRenderbuffers(1, &rb1);
		glBindRenderbuffer(GL_RENDERBUFFER, rb1);
		glRenderbufferStorageMultisample(GL_RENDERBUFFER, 4, GL_DEPTH24_STENCIL8, 1024, 1024);
		//glRenderbufferStorage(GL_RENDERBUFFER, GL_DEPTH24_STENCIL8, 1024, 1024);
 
 
		glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, rb1);
		glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_STENCIL_ATTACHMENT, GL_RENDERBUFFER, rb1);
 
 
		glReadBuffer(GL_NONE);
		glDrawBuffer(GL_NONE);
 
 
		GLenum fboStatus1 = glCheckFramebufferStatus(GL_FRAMEBUFFER);
		assert(fboStatus1 == GL_FRAMEBUFFER_COMPLETE);
 
 
		check_gl_error();
	}
 
 
	GLuint fbo2 = 0;	
 
 
	// setup FBO 2
	{		
		glGenFramebuffers(1, &fbo2);
		glBindFramebuffer(GL_FRAMEBUFFER, fbo2);
 
 
		GLuint rb2 = 0;	
		glGenRenderbuffers(1, &rb2);
		glBindRenderbuffer(GL_RENDERBUFFER, rb2);
		glRenderbufferStorageMultisample(GL_RENDERBUFFER, 4, GL_DEPTH24_STENCIL8, 1024, 1024);
		//glRenderbufferStorage(GL_RENDERBUFFER, GL_DEPTH24_STENCIL8, 1024, 1024);
 
 
		glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, rb2);
		glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_STENCIL_ATTACHMENT, GL_RENDERBUFFER, rb2);
 
 
		glReadBuffer(GL_NONE);
		glDrawBuffer(GL_NONE);
 
 
		GLenum fboStatus2 = glCheckFramebufferStatus(GL_FRAMEBUFFER);
		assert(fboStatus2 == GL_FRAMEBUFFER_COMPLETE);
 
 
		check_gl_error();
	}
 
 
	glBindFramebuffer(GL_FRAMEBUFFER,0);
 
 
	glBindFramebuffer(GL_READ_FRAMEBUFFER, fbo1);
	glBindFramebuffer(GL_DRAW_FRAMEBUFFER, fbo2);
 
 
	GLenum readStatus = glCheckFramebufferStatus(GL_READ_FRAMEBUFFER);
	assert(readStatus == GL_FRAMEBUFFER_COMPLETE);
 
 
	GLenum drawStatus = glCheckFramebufferStatus(GL_DRAW_FRAMEBUFFER);
	assert(drawStatus == GL_FRAMEBUFFER_COMPLETE);
 
 
	check_gl_error();
 
 
	// crash here
	glBlitFramebuffer(0, 0, 1024, 1024, 0, 0, 1024, 1024, GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT, GL_NEAREST);

Is this code somehow incorrect, or is this probably a bug in AMD's drivers?

In general, unless you're throwing a pointer at the implementation, a crash is always a driver bug.

[Nowhere-01]

try blitting depth and stencil separately in two glBlitFramebuffer calls. if it works, report here a driver bug. i've already seen topics mentioning that AMD drivers fail to blit depth and stencil together.

It crashes when blitting just depth too. I added the stencil bit thinking maybe the problem was with blitting just one half of the packed depth-stencil buffer. I reported at the AMD forums already, I was just hoping someone here might spot something in my usage that isn't correct.
