glTextureViewOES on DEPTH24_STENCIL8

I am working on an application which requires bit-casting some texture formats to others. One of these reinterpretations is DEPTH24_STENCIL8 to RGBA8. I implemented the reinterpretation by creating a texture view of the DEPTH24_STENCIL8 texture and setting GL_DEPTH_STENCIL_TEXTURE_MODE to GL_STENCIL_INDEX for the view. Then I sample both the depth texture and the stencil view in a shader that performs the reinterpretation.

glTextureViewOES(stencil, GL_TEXTURE_2D, depth, GL_DEPTH24_STENCIL8, 0, 1, 0, 1);

glActiveTexture(GL_TEXTURE1);
glBindTexture(GL_TEXTURE_2D, stencil);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
glTexParameteri(GL_TEXTURE_2D, GL_DEPTH_STENCIL_TEXTURE_MODE, GL_STENCIL_INDEX);

According to the texture view specification this should be supported as long as I'm not making a view of a different format from the depth/stencil texture.

However, the driver spits out this message:


API ERROR 2147483647: incompatible view classes

And the stencil view is not sampled.

Is this a driver bug, or am I doing something wrong?
