<pre>When I run glDrawPixels(width, height, GL_COLOR_INDEX, GL_UNSIGNED_BYTE, data)
code execution never return.
Commit 84eb402c01962e3ff4b70c9948c85a61ed81678f changed the path so we end up
in _mesa_format_from_format_and_type at src/mesa/main/glformats.c:2682 which
does not seem to know anything about GL_COLOR_INDEX. On release build this
function should return a value but doesn't and gets confused, on debug build I
get assert _mesa_format_from_format_and_type: Assertion `!"Unsupported format"'
failed.
I made minimalistic test for this, one can get it from here
<a href="https://github.com/juhapekka/CI_test.git">https://github.com/juhapekka/CI_test.git</a>
There seems also exist test in Piglit which does similar and halts Piglit run.
Piglit test is gl-1.0-drawpixels-color-index</pre>
