Daniel,

I have been trying to follow this string but am not sure what the current
status is.  I have been having a bootstrap failure on IA64 HP-UX (when
building the Fortran runtime library) since version r137859 went in.

It looks like there are known problems with this patch, is there a fix
coming for the known problems or would information on the problem
I am seeing be useful?  I am getting a segmentation violation in
get_constant_for_value_id.

Program received signal SIGSEGV, Segmentation fault
  si_code: 2 - SEGV_ACCERR - Invalid Permissions for object.
