catch unaligned (idb mode only)

Syntax

catch unaligned

Parameters

None

Example

This command catches unaligned accesses. It is very similar to the stop unaligned command.

This command differs from a normal catch command in the following ways:

• unaligned is not the name of a signal.

• There is no corresponding signal number.

• unaligned is never listed by either the catch or ignore commands without a parameter.

Like other catch commands, the following rules apply:

• The debugger does not make an entry in the breakpoint table for a catch command.

• Repeating the command does not create an additional breakpoint.

You cannot specify unaligned in a signal detector of a normal breakpoint definition.

The default is catch unaligned. To override the default and tell the debugger to ignore unaligned accesses, use the following command:

(idb) ignore unaligned

However, if a breakpoint was defined using an unaligned access detector, then it must be disabled using a disable or delete breakpoint command.

Unaligned accesses are automatically handled and quietly corrected on Linux* OS. The debugger cannot catch these events.
