Description dcb314 2005-09-28 06:08:39 UTC 
I just tried to compile Fedora development package xorg-x11-6.8.2-54
with a special non-standard version of the usual GNU C compiler.

The compiler said

gamma_state.c:1593: warning: array subscript out of range

The source code is

        WRITE(gmesa->buf, TxBaseAddr12, curTex->TextureBaseAddr[12]);

but

../BUILD/xorg-x11-6.8.2/xc/lib/GL/mesa/drivers/dri/gamma/gamma_context.h:  
uint32_t TextureBaseAddr[GAMMA_TEX_MAXLEVELS];

and

../BUILD/xorg-x11-6.8.2/xc/lib/GL/mesa/drivers/dri/gamma/gamma_context.h:#define
GAMMA_TEX_MAXLEVELS 12

so TextureBaseAddr[12] doesn't exist.  Suggest code rework.

This was fixed in Mesa CVS a while back.  The fix will be in Mesa 6.4 and the
next X.org release.
