<pre>I was trying to reproduce <a class="bz_bug_link
bz_status_NEW "
title="NEW - witcher 2 glitches a lot"
href="show_bug.cgi?id=91310">bug #91310</a> on my NV92, but the game fails to start
for me, terminal shows:
witcher2: main/teximage.c:1320: init_teximage_fields_ms: Assertion
`img->_BaseFormat != -1' failed.
The game starts properly when using the llvmpipe driver.
The problem was introduced by
commit 3473a84fb2c2cdab0bcecb43fbf519d9b3fc0142

mesa: Fix incorrect assertion in init_teximage_fields_ms
_BaseFormat is a GLenum (unsigned int) so testing if its value is
greater than 0 to detect the cases where _mesa_base_tex_format
returns -1 doesn't work.
Fixing the assertion breaks the arb_texture_view-lifetime-format
piglit test on nouveau, since that test calls
_mesa_base_tex_format with GL_R16F with a context that does not
have ARB_texture_float, so it returns -1 for the BaseFormat, which
was not being caught properly by the ASSERT in init_teximage_fields_ms
until now.
Reverting the patch on Mesa 10.5.9 fixes the issue for me.
