IIRC this happens because the spec dictates that the stack depth must be 1 to begin with, at which point we detect that we should 'do_log' in _mesa_error() which effectively adds the debug message. Might be worth checking how other implementations behave in such a case (just do anything illegal) and read through the spec what the exact behaviour should be. Just some ideas, I'm busy with something else atm :-\</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>
