spvtools fuzzers crashing on most runs |
||||
Issue descriptionIt looks like the spvtools fuzzers are crashing very frequently. e.g. https://clusterfuzz.com/v2/performance-report/libFuzzer_spvtools_opt_size_fuzzer/libfuzzer_chrome_asan/2018-10-28 This needs to be fixed so that it can explore more codepaths without being blocked.

K, we'll take a look at the filed bugs. The logs don't give the test cases that I can see, just a stacktrace? Thanks, dan

The logs don't have the testcases, but the bugs have them.

We've fixed a bunch of the blocking bugs. One remaining one is a large refactor to fix that we're working on. I don't see any input files linked from the logs so there is nothing we can do with those. Please file bugs with attached reproduction cases if you still think the crash rate is too high. |
