+ <para>The <emphasis>tst-aio9</emphasis> and

Threads.</para>

+ <listitem>
+ <para>The <emphasis>elf/check-localplt</emphasis> and
+ <emphasis>c++-types-check</emphasis> tests will fail with Linux
+ Threads because binary symbols do not match what is expected when

+ <listitem>
+ <para>The <emphasis>nptl/tst-clock2</emphasis> and
+ <emphasis>tst-attr3</emphasis> tests sometimes

checks ELF dynamic symbol tables against expected values. See:
