Description:
I accidentally included single quotations in the "From Host" field when creating a user account. Now I have a user account with the "From Host" field = '%' (notice the literal single quotations). Whenever I attempt to select this user account in the workbench, to delete/change the account, an unhandled exception occurs and the application crashes. Of note, I've attempted to delete this account from the cmd line, but a 1396 error (unable to drop user) occurs. The inner exception I get is:
System.AccessViolationException was unhandled
Message=Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

InnerException:
How to repeat:
Create a user with any username and a "from host" field ='%' . Then select this user account in the Server Access Management Tab.
Suggested fix:
Include validation in the "From Host" field before users can add accounts with illegal/troublesome formats.
