    Description

      With respect to a test failure in evergreen:
      https://evergreen.mongodb.com/task_log_raw/wiredtiger_macos_1012_unit_test_acc6f67c4169af3f3ba96e21089c00ef8bcafca7_18_02_26_22_43_52/0?type=T&text=true

      The error seen is as follows:

      The assertion has a truncated error message not long enough to determine the cause. This instance required us to fetch the core and debug for the error. It will be awesome if we can include more information so that it is obvious from the assertion what went wrong.
