    What are the warnings and failures? Without them there is nothing we can fix or troubleshoot.

    @hebasto Thanks for reporting. We test with --with-sanitizers=thread in the Travis ci/test/00_setup_env_native_tsan.sh job, so if this turns out to be a general issue then it would be interesting to know why the ThreadSanitizer Travis job didn’t fail :)

    Sorry. Initially, the GH failed to upload the whole log.

    Here is a typical excerpt from the log:

86SUMMARY: ThreadSanitizer: lock-order-inversion (potential deadlock) (/home/hebasto/GitHub/bitcoin/src/test/test_bitcoin+0xc5d0e) in __interceptor_pthread_rwlock_wrlock
87==================
  6. hebasto commented at 7:01 pm on April 30, 2020: member

    @hebasto Thanks for reporting. We test with --with-sanitizers=thread in the Travis ci/test/00_setup_env_native_tsan.sh job, so if this turns out to be a general issue then it would be interesting to know why the ThreadSanitizer Travis job didn’t fail :)

    After adding --disable-wallet to the configure options all of the libdb-related warnings gone. Do we have documented it somewhere?

    The remaining warnings are only from the sync_tests:

     0$ ./configure --disable-wallet --with-sanitizers=thread --disable-asm CC=clang-8 CXX=clang++-8
 1$ make clean && make
 2$ ./src/test/test_bitcoin --run_test=sync_tests
 3Running 1 test case...

    I don’t think it is possible to run tsan on BDB.

    Have you seen the suppressions in ./test/sanitizer_suppressions/tsan?

    Closing in favor of #19047 which has cleaner problem description.
