--- Comment #6 from Marcus Plutowski <marcus_plutowski at apple.com> ---
I'll take a look. This assert firing means that the AssemblerBuffer (where we emit code before it gets linked) contains an unexpectedly long string of 0s -- 16 or more, which should not be valid x86 ASM. A few questions:
  1. Does this reproduce locally, or just on the test runner?
  2. Does this reproduce when run alone, or only when run as part of a large batch of tests running in parallel?
  3. Is it possible for me to see the .ips files which resulted from the crashes in the link https://results.webkit.org/?platform=mac&suite=layout-tests&test=fast%2Fcanvas%2Fimage-buffer-backend-variants.html ?
