    Current master, Ubuntu:

    Repeatedly running validation_block_tests/processnewblock_signals_ordering, a test that creates multiple threads to test the validation interface, sporadically writes weird messages to stdout (with the test passing). Running for i in {1..30}; do ./src/test/test_bitcoin --run_test=validation_block_tests/processnewblock_signals_ordering; done usually gives me multiple occurrences of this.

    It sometimes writes code fragments such as “pindexNew->GetBlockHash()”, “m_expected_tip”, “==”, in other runs single log entries.

    Can someone reproduce this? Obviously this is just a small nuisance in itself, still reporting this in case the root cause might be interesting.
