So I built mesa with debug symbols and I guess debugging enables some assertions because now fails at some assertion about Register.Index stuff. Full backtrace attached. (<a class="bz_bug_link bz_status_NEW " title="NEW --- - TGSI constant buffer overrun causes LLVM assertion failure" href="show_bug.cgi?id=81834">bug 81834</a> doesn't say what versions he uses. I use upstream llvm 214022 and mesa git with the small patch I mentioned) Of course it could be both problems at the same time.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
