Cr bug: http://code.google.com/p/chromium/issues/detail?id=93830 There's a crashing layout test on mac in the gpu config, tested with chromium r97735 + WebKit r93540. Avi says it's related to a known issue. To reproduce this crash build DumpRenderTree (the target is in third_party/WebKit/Source/WebKit/chromium/WebKit.xcodeproj) and run it with the following flags: --test-shell --pixel-tests=/usr/local/home/jamesr/chrome/src/webkit/Debug/layout-test-results/png_result0.png --enable-accelerated-2d-canvas --enable-accelerated-compositing then pass the following two lines to stdin (separate lines): $CHROME_REPOSITORY_ROOT/src/third_party/WebKit/LayoutTests/compositing/animation/busy-indicator.html $CHROME_REPOSITORY_ROOT/src/third_party/WebKit/LayoutTests/compositing/iframes/iframe-size-to-zero.html The crashing stack is: #0 0x9069cf8b in objc_msgSend () #1 0x0032a5e0 in ??
