Known Problems in WDB 5.1

The internal format of the register context changed between 11.22 and 11.23 to support new scratch registers (ar.csd/ar.ssd) and lazy FP. Libuca changed to match the new format and does not support the old format.

Work Around

• If you need to debug an 11.22 core file, you need an 11.22 libuca.

• If you need to debug an 11.23 core file, you need an 11.23 libuca.
