Descrizione

Test case file: clusterfuzz-testcase-ext_proc_unit_test_fuzz-5199582416928768.txt

fuzzer generated all dots 1Mb stats prefix. It needs to be limited to avoid excessive CPU cleanup of the stats store.

Steps to reproduce:

Copy downloaded test case file into the test/extensions/filters/http/ext_proc/unit_test_fuzz/ext_proc_corpus/ directory and run:

bazel build --config=asan -c dbg test/extensions/filters/http/ext_proc/unit_test_fuzz/ext_proc_unit_test_fuzz
bazel-bin/test/extensions/filters/http/ext_proc/unit_test_fuzz/ext_proc_unit_test_fuzz test/extensions/filters/http/ext_proc/unit_test_fuzz/ext_proc_corpus/clusterfuzz-testcase-ext_proc_unit_test_fuzz-5199582416928768.txt
