It also dies with draw using llvm (same address), but ... harder to debug that. Will try to investigate further. Since this is a client-side buffer, could be the application doing something illegal.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
