Fuzz tests all fail

I want to run the fuzz tests so I can see examples of how the fuzzer is working.

I cloned DynamoRIO/drmemory from GitHub (https://github.com/DynamoRIO/drmemory) and followed the procedure for building on linux (https://github.com/DynamoRIO/drmemory/wiki/How-To-Build) without making any source code changes. The build completed OK and I'm able to run tests ("make tests") and all the tests with names "fuzz_*" failed. I'm running on Ubuntu 18:

"Linux tneale-vb 4.15.0-144-generic #148-Ubuntu SMP Sat May 8 02:33:43 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux"

Are these tests supposed to pass?

I'm attaching a log of the test run and log files from a single test out of the run, fuzz_corpus.

Thanks for your help!

You can see the automated tests pass on the Github Actions VM: https://github.com/DynamoRIO/drmemory/runs/2695175875?check_suite_focus=true#step:7:4798

Thanks, that is helpful. I was looking at the tutorial page:

https://dynamorio.org/page_tutorial_secdev16.html

And the files pointed are now missing, except for the instructions page, which refers to demo files SecDev16/Demo, but that link is also broken. Are these files (or some updated version) available somewhere?
