Couldn't reproduce a leak in SwiftShader (libGLESv2.so or libEGL.so). Only got several in chrome.

Labels: Needs-Feedback
ClusterFuzz testcase 5803513008095232 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.

If you suspect that the result above is incorrect, try re-doing that job on the test case report page.
Assuming this was fixed by https://chromium-review.googlesource.com/1194698, which would mean it was a Clang bug. We may also see this re-appear if the Clang upgrade simply changed the stack trace signature.
