Don't raise an error for optimized out sub-fields.
http://sourceware.org/ml/gdb-patches/2013-07/msg00317.html
gdb/ChangeLog
* value.c (value_fetch_lazy): Mark optimized out values as such
rather than raising an error.
gdb/testsuite/ChangeLog
* gdb.dwarf2/pieces-optimized-out.exp: Expect "<optimized out>"
when printing an optimized out value. Expect an error when using
an optimized out value in an expression.
