<pre>Hi, Kenneth,
We reproduce this issue in below scene, crash happens in the second
generateMipmap.
tex = gl.createTexture();
gl.bindTexture(gl.TEXTURE_2D, tex);
gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA8, 8, 8, 0, gl.RGBA,
gl.UNSIGNED_BYTE, new Uint8Array(8 * 8 * 4));
gl.generateMipmap(gl.TEXTURE_2D);
wtu.glErrorShouldBe(gl, gl.NO_ERROR, "generateMipmap should succeed");
if (gl.getExtension('EXT_color_buffer_float') &&
gl.getExtension('OES_texture_float_linear')) {
gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA32F, 0, 0, 0, gl.RGBA, gl.FLOAT,
null);
gl.generateMipmap(gl.TEXTURE_2D);
wtu.glErrorShouldBe(gl, gl.NO_ERROR, "generateMipmap should succeed for
zero-size texture");
}</pre>
