For this benchmark, there is 1 normal class, and 4 error classes. The error classes are described below. An alpha version of Microsoft Visual FoxPro 9 (tm) was used.
| Class description | Resulting Behavior | |
|---|---|---|
| 1 | Attempting to save a Table to a read-only file | Dialog box indicates a "non-fatal" Access Violation has occured, program continues to execute |
| 2 | Attempting to save a Form to a file that is open by another program | Access Violation, program terminates |
| 3 | This synthetic error class induces a bug, to simulate memory corruption. Setting memory location to 0 (the variable is used as a function pointer during screen refresh) | Access Violation when screen is being refreshed |
| 4 | This synthetic error class induces a bug, to simulate a misbehaving extension. Setting memory location to 1 (the variable is normally 0, and is used as a an optional "hook" function pointer. | Access Violation when "bad" hook function pointer is used |
