[Bug libgomp/29986] testsuite failures

["ro at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #5 from ro at gcc dot gnu dot org  2010-01-26 15:35 -------
I've found that the problem doesn't occur when assembler patch 118683-03 is
installed.  If I compare the relocations produced by as from patch 118683-02
with
those produced by patch 118683-03, I find some differences (elfdump -r output):

 Relocation Section:  .rela.eh_frame

In the broken object, the relocations are relative to the .tbss section, in the
working one, they are relative to a symbol.

I strongly suppose this is due to the fix for 

6728528  assembler does not handle __thread code correctly

although

  http://bugs.sun.com/view_bug.do?bug_id=6728528

doesn't provide much detail.
