Creating a database whose name consists of a single ASCII control character will fail on wiredTiger when using directoryperdb. The resulting error message is: 2015-01-06T15:57:47.849-0500 E STORAGE [conn1] WiredTiger (22) [1420577867:849716][8582:0x7f7f6cee1700], session.create: Error parsing 'source="file:/collection-2--8284435167946820371.wt"' at byte 13: Unexpected character: Invalid argument 2015-01-06T15:57:47.849-0500 I - [conn1] Assertion: 2:22: Invalid argument 2015-01-06T15:57:47.850-0500 I WRITE [conn1] insert .col query: { _id: ObjectId('54ac4c4b45b361825ef700be'), data: true } ninserted:0 keyUpdates:0 exception: 22: Invalid argument code:2 249ms Either disabling directoryperdb or using mmapv1 prevents this error from occurring.

Compile the attached C++ program. This program will take a hex code as an argument and create a database whose name is the character represented by the hex code. Start mongod with --directoryperdb and --storageEngine wiredTiger Run ./unprintable 07
