Hello, this CL should only have effect on platforms using constant pool. Apparently, ppc is the only platform enabling constant pool by default.

And I have no permission to see the detailed report.

The test case only takes 0.2 seconds to complete on my machine, even though it executes a number of grow_memory instructions.
Cannot test with msan, because it's still not supported on rodete.
Marking WontFix for now.

Labels: Needs-Feedback
ClusterFuzz testcase 5162984113176576 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.
