Looks like +1 for O2. Can you do "i threads" when it crashes? Are any other threads compiling shaders at the same time? It appears that the last linked fragment shader is from fragment shader 2749, which is not the last glsl shader source to have been provided. Which is odd, but not impossible. [Not 100% sure, but I think it's linked with vertex shader 2693.] Need to run through through piglit and see what happens. However they look simple enough. Could you poke around a bit more in gdb and see if there's anything interesting?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
