msarett@'s change does not look to be related.

Although this crashes in Skia, this is probably due to a large width/height used to allocate a bitmap.

The width and height are computed from the cull rect of the SkPicture [1], which may be large.

Status: WontFix (was: Untriaged)
ClusterFuzz testcase 6453387888689152 is flaky and no longer crashes, so closing issue.

If this is incorrect, please add ClusterFuzz-Wrong label and re-open the issue.
