Step #10: + check_startup_crash /workspace/out/memory/parse_UTF_16LE_fuzzer
Step #10: + local FUZZER=/workspace/out/memory/parse_UTF_16LE_fuzzer
Step #10: + local CHECK_PASSED=0
Step #10: + [[ libfuzzer = libfuzzer ]]
Step #10: ++ /workspace/out/memory/parse_UTF_16LE_fuzzer -runs=4
Step #10: ++ egrep 'Done 4 runs' -c
Step #10: BAD BUILD: the fuzzer seems to have either startup crash or exit.
Step #10: + CHECK_PASSED=0
Step #10: + ((  0 == 0  ))
Step #10: + echo 'BAD BUILD: the fuzzer seems to have either startup crash or exit.'
Step #10: + exit 1

It is crashing all the time when testing the very first input: https://oss-fuzz.com/v2/performance-report/libFuzzer_expat_parse_UTF_8_fuzzer/libfuzzer_msan_expat/latest
