[1509979950:270171][27385:0x7f7ac7fff700], WT_SESSION.commit_transaction: commit timestamp 5e296 older than oldest timestamp: Invalid argument
test_timestamp_abort: FAILED: thread_run/323: session->commit_transaction(session, tscfg): Invalid argument

Both test_timestamp_abort and test/format likely need the same fix. They were fixed in WT-3672 but there must still be a place where the compiler can/will reorder statements.

Also it would be nice if the "older than oldest timestamp" actually printed out the oldest timestamp value in the error message. Same thing with the other statements like stable timestamp.
