--- Comment #1 from Rainer Orth <ro at gcc dot gnu.org> 2012-01-27 11:37:09 UTC ---
Ian has now provided a detailed investigation of the problem:

  http://gcc.gnu.org/ml/gcc-patches/2012-01/msg00918.html

For the 64-bit Solaris/x86 case, Solaris engineering has identified and fixed
the bug:

7133114 fsbase (%fs:0) is not set properly after makecontext()/setcontext()

The fix will be in Solaris 11 Update 1, and I've requested a Solaris 10
Update 10 backport, which will be delivered as a patch on top of patch
144501-19.
