-    fix memory errors with demangled name hash
-    
-    This fixes a regression that Jan pointed out.
-    
-    The bug is that some names were allocated by dwarf2read on the objfile
-    obstack, but then passed to SYMBOL_SET_NAMES with copy_name=0.  This
-    violates the invariant that the names must have a lifetime tied to the
-    lifetime of the BFD.
-    
-    The fix is to allocate names on the per-BFD obstack.
-    
-    I looked at all callers, direct or indirect, of SYMBOL_SET_NAMES that
-    pass copy_name=0.  Note that only the ELF and DWARF readers do this;
-    other symbol readers were never updated (and perhaps cannot be,
-    depending on the details of the formats).  This is why the patch is
-    relatively small.
-    
-    Built and regtested on x86-64 Fedora 20.

-Running gdb.threads/thread-execl.exp with scheduler-locking set to
-"step" reveals a problem:

- (gdb) next^M
- [Thread 0x7ffff7fda700 (LWP 27168) exited]^M
- [New LWP 27168]^M
- [Thread 0x7ffff74ee700 (LWP 27174) exited]^M
- process 27168 is executing new program: /home/jkratoch/redhat/gdb-clean/gdb/testsuite/gdb.threads/thread-execl^M
- [Thread debugging using libthread_db enabled]^M
- Using host libthread_db library "/lib64/libthread_db.so.1".^M
- infrun.c:5225: internal-error: switch_back_to_stepped_thread: Assertion `!schedlock_applies (1)' failed.^M
- A problem internal to GDB has been detected,^M
- further debugging may prove unreliable.^M
- Quit this debugging session? (y or n) FAIL: gdb.threads/thread-execl.exp: schedlock step: get to main in new image (GDB internal error)
-
-The assertion is correct.  The issue is that GDB is mistakenly trying
-to switch back to an exited thread, that was previously stepping when
-it exited.  This is exactly the sort of thing the test wants to make
-sure doesn't happen:
-
-	# Now set a breakpoint at `main', and step over the execl call.  The
-	# breakpoint at main should be reached.  GDB should not try to revert
-	# back to the old thread from the old image and resume stepping it
-
-We don't see this bug with schedlock off only because a different
-sequence of events makes GDB manage to delete the thread instead of
-marking it exited.
-
-This particular internal error can be fixed by making the loop over
-all threads in switch_back_to_stepped_thread skip exited threads.
-But, looking over other ALL_THREADS users, all either can or should be
-skipping exited threads too.  So for simplicity, this patch replaces
-ALL_THREADS with a new macro that skips exited threads itself, and
-updates everything to use it.
-
-Tested on x86_64 Fedora 20.
