The difference appears to be in error messages:

# Difference:

+ /mnt/scratch0/clusterfuzz/slave-bot/inputs/fuzzer-testcases/d4965d4961e1ee8f70185a462d26173bfuzz-06475.js:7: TypeError: Cannot read property 'Symbol(Symbol.iterator)' of (intermediate value)(intermediate value)

Still would be nice to fix, but seems of lower priority.

Actually, I take this to figure out how to suppress the phrase (intermediate value)(intermediate value) in the output.

Labels: Needs-Feedback
ClusterFuzz testcase 4819218100125696 is still reproducing on tip-of-tree build (trunk).

If this testcase was not reproducible locally or unworkable, ignore this notification and we will file another bug soon with hopefully a better and workable testcase.

Otherwise, if this is not intended to be fixed (e.g. this is an intentional crash), please add ClusterFuzz-Ignore label to prevent future bug filing with similar crash stacktrace.
