The following code causes a crash 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 there somewhere I can file this as a bug report? I've uploaded a self-contained VC10 project that reproduces the crash.

Thanks,
