Yes.  Here is the last part of the output from my buildbot testing ZODB 
trunk and ZODB 3.9 on Windows:

Tests with errors:
    test_restoreBlob_shared 
(relstorage.tests.test_blobhelper.BlobHelperTest)
    test_storeBlob_replace (relstorage.tests.test_blobhelper.BlobHelperTest)
    test_storeBlob_shared (relstorage.tests.test_blobhelper.BlobHelperTest)
    test_storeBlob_unshared 
(relstorage.tests.test_blobhelper.BlobHelperTest)
    test_vote (relstorage.tests.test_blobhelper.BlobHelperTest)
Total: 583 tests, 0 failures, 5 errors in 20 minutes 1.718 seconds.

The tests of ZODB 3.8 produce the same errors except 
test_storeBlob_unshared (since unshared blobs don't work in ZODB 3.8).
