The debug internals interface signals conditions when it can’t adhere to its contract. These are serious-conditions because the program using the interface must handle them before it can correctly continue execution. These debugging conditions are not errors since it is no fault of the programmers that the conditions occur. The interface does not provide for programs to detect these situations other than calling a routine that detects them and signals a condition.
This condition inherits from serious-condition, and all debug-conditions inherit from this. These must be handled, but they are not programmer errors.
This condition indicates there is absolutely no debugging information available.
This condition indicates the system cannot return values from a frame since its debug-function lacks debug information details about returning values.
This condition indicates that a function was not compiled with debug-block information, but this information is necessary necessary for some requested operation.
Similar to no-debug-blocks
, except that variable information was
requested.
Similar to no-debug-blocks
, except that lambda list information was
requested.
This condition indicates a debug-variable has :invalid
or :unknown
value in a particular frame.
This condition indicates a user supplied debug-variable name identifies more than one valid variable in a particular frame.
