Not at all sure if this is a fuzzer library issue, but it is a fuzzer out of memory issue (not the code running out of memory, at least not directly).

Re-assign as necessary.

This seems like another dupe of 835418, in SkDashImpl::CreateProc allocating too much memory.

ClusterFuzz testcase 6688552418279424 is flaky and no longer crashes, so closing issue.

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