The crash should be fixed in master now. I can confirm that the segfault is gone. However, the demo does not render properly(I don't know if I should make another report for that). I'll upload an other trace, as the first one was generated on PITCAIRN and has alignment issue when replaying it on REDWOOD. The problem seems to be at Frame 0, call 2875: garbage is generated on attached texture on REDWOOD and render fine on PITCAIRN. Created attachment 136302 [details]

Created attachment 136265 [details] Apitrace of the demo This demo requires GLSL 430, so it will only works with mesa git on evergreen. I have this crash with REDWOOD and JUNIPER chips. The demo works fine on others drivers (tested on radeonsi and intel). I've got this while debugging with GDB: "Thread 1 "Sample_Tutorial" received signal SIGSEGV, Segmentation fault. r600_decompress_color_images (rctx=rctx@entry=0x7c82b0, images=images@entry=0x7c92b0) at r600_blit.c:420 420 r600_blit_decompress_color(&rctx->b.b, tex," I've attached an apitrace. The crash occurs at frame 0, call 2983. The other Ogre UAV demo (TutorialUAV02), does not have this problem.
