- <a name="index-Ada-tasking-and-core-file-debugging"></a>
-
- <p>When inspecting a core file, as opposed to debugging a live program,
- tasking support may be limited or even unavailable, depending on
- the platform being used.
- For instance, on x86-linux, the list of tasks is available, but task
- switching is not supported.
- </p>
- <p>On certain platforms, the debugger needs to perform some
- memory writes in order to provide Ada tasking support. When inspecting
- a core file, this means that the core file must be opened with read-write
- privileges, using the command ‘<samp>"set write on"</samp>’ (see <a href="Patching.html#Patching">Patching</a>).
- Under these circumstances, you should make a backup copy of the core
- file before inspecting it with <small>GDB</small>.
