<h5 class="subsubsection">15.4.10.8 Tasking Support when Debugging Core Files</h5>
<p><a name="index-Ada-tasking-and-core-file-debugging-1079"></a>
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>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 &lsquo;<samp><span class="samp">"set write on"</span></samp>&rsquo; (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 <span class="sc">gdb</span>.
