Red Hat Bugzilla – Bug 112908
subscript out of range at compile time
Last modified: 2007-11-30 17:10:35 EST
Description of problem: I just tried to compile package XFree86-4_3_0-37 from Fedora. The compiler said gamma_state.c(1599): warning #175: subscript out of range The source code is WRITE(gmesa->buf, TxBaseAddr12, curTex->TextureBaseAddr[12]); but [root@localhost SPECS]# find ../BUILD/XFree86-4.3.0/xc/ -name \*.h -print | xargs grep TextureBaseAddr ../BUILD/XFree86-4.3.0/xc/lib/GL/mesa/src/drv/gamma/gamma_context.h: CARD32 TextureBaseAddr[GAMMA_TEX_MAXLEVELS]; and [root@localhost SPECS]# find ../BUILD/XFree86-4.3.0/xc/ -name \*.h -print | xargs grep GAMMA_TEX_MAXLEVELS ../BUILD/XFree86-4.3.0/xc/lib/GL/mesa/src/drv/gamma/gamma_context.h:#define GAMMA_TEX_MAXLEVELS 12 So curTex->TextureBaseAddr[12] doesn't exist. I'm not sure what the fix is for this. Version-Release number of selected component (if applicable): How reproducible: Every time. Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
If you are compiling XFree86 yourself, either from raw sources, or from our RPMs, modified or unmodified, and you require assistance and/or technical support to get something to compile, you can post a message to one of the Red Hat and/or XFree86 mailing lists, such as xfree86-list@redhat.com, redhat-list@redhat.com, fedora-list@redhat.com, xfree86@xfree86.org or others. While bugzilla is not a technical support forum for these types of problems, our mailing lists definitely are, and there are many people who read our mailing lists and may be able to assist you with problems of this nature. Closing bug report as 'NOTABUG'
Mike, the object of this bug report is not that the warning occurs, but that a non-existent array member is accessed.

I think I have found a bug in XFree-86. I thought I had found the right place to submit the bug report. According to your most generous instructions above, it still looks like I have found the right place to report it. I have decided to re-open the bug report. If I am still wrong, then my apologies, and I will try to report it to the mailing lists you mention above.
If there is no specific bug caused from this problem, such as a system lockup, X server crash, or visible on screen corruption, then it should be reported directly to XFree86.org using their bugzilla at http://bugs.xfree86.org Unless there is a known and reproduceable system crash caused, then these types of issues are very low priority and unless there is a patch attached which fixes the problem without causing further regressions, it will be of very low priority, and is likely to sit in bugzilla for a very long time. Even so, you should still report it, and any similar reports directly to XFree86.org in their bugzilla, and then put the URL to the upstream bug report here for it to be tracked upstream. There are an enormous amount of compiler warnings generated when compiling XFree86, and the best place to report them is upstream, preferably (but not necessarily) with patches that fix the problems in a clean and clear way. Once you've reported this upstream, please include the upstream bug URL here and I will track upstream progress on this.
