This is what I did for <a class="bz_bug_link bz_status_RESOLVED bz_closed" title="RESOLVED FIXED - X server crash in nouveau_xv.c:NVPutImage (NVCopyNV12ColorPlanes)" href="show_bug.cgi?id=63263">bug 63263</a> (see my initial comment there), and that was able to pinpoint the crash exactly. (Of course figuring out the circumstances that lead to that condition can be trickier to work out.) You can also compile the whole thing with -g, e.g. ./configure CFLAGS=-g or something like that. And make sure that the final thing isn't stripped. That might make gdb more cooperative if you're having trouble.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
