What surprises me a bit is that it seems to kick off rendering with GPU as isl_emit_depth_stencil_hiz_s() gets called to setup the hardware. For normal rendering there is its own path for setting depth+stencil and ending up here means that the GPU is being setup for blorp. Anyway, is ~Texture() really suppose to render something and more importantly is the driver context still suppose to be valid at this point. Looking at: 6 0x00007f294cfdb534 in isl_gen5_emit_depth_stencil_hiz_s (dev=0x0, batch=0x1344830, info=0x1) at /var/tmp/portage/media-libs/mesa-9999/work/mesa-9999/src/intel/isl/isl_emit_depth_stencil.c:67 All three arguments are pointers and must be valid, first is simply NULL and third clearly invalid "0x1".</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
