The SET_OF_INVALID_CONTEXT bug check has a value of 0x00000030. This indicates that the stack pointer in a trap frame had an invalid value.
The following parameters are displayed on the blue screen.
| Parameter | Description |
|---|---|
| 1 | The new stack pointer |
| 2 | The old stack pointer |
| 3 | The trap frame address |
| 4 | 0 |
This bug check occurs when some routine attempts to set the stack pointer in the trap frame to a lower value than the current stack pointer value.
If this error were not caught, it would cause the kernel to run with a stack pointer pointing to stack which is no longer valid.
