+ As reported by Harald Hanche-Olsen in
+ <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00445.html>
+ the change introduces a further bug, of creating lots of zombie
+ processes in some cases. Further work is needed to come up with a
+ better fix for Bug#8855.

+ Fix a race condition with glib (Bug#8855).
+ The symptom is a diagnostic "GLib-WARNING **: In call to
+ g_spawn_sync(), exit status of a child process was requested but
+ SIGCHLD action was set to SIG_IGN and ECHILD was received by
+ waitpid(), so exit status can't be returned." The diagnostic
+ is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
+ The real bug is a race condition between Emacs and glib: Emacs
+ does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
+ so that glib can't find it. Work around the bug by invoking
+ waitpid only on subprocesses that Emacs itself creates.
+
+ This is a backport from the trunk, consisting of:
+
+ * w32proc.c (create_child): Don't clip the PID of the child
+ process to fit into an Emacs integer, as this is no longer a
+ restriction.
+ (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
+ reaping only the process specified by PID argument, if that is
+ positive. Use PID instead of dead_child to know which process to
+ reap. Wait for the child to die only if WNOHANG is not in
+ OPTIONS.
+ (sys_select): Don't set dead_child.
+
+ * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
+ as it is no longer needed.
+
+ * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
+ no longer needed.
+ (create_process, record_child_status_change): Don't use special
+ value -1 in pid field, as the caller now must know the pid rather
+ than having the callee infer it. The inference was sometimes
+ incorrect anyway, due to another race.
+ (create_process): Set new 'alive' member if child is created.
+ (process_status_retrieved): New function.
+ (record_child_status_change): Use it.
+ Accept negative 1st argument, which means to wait for the
+ processes that Emacs already knows about. Move special-case code
+ for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
+ processes that have already been waited for, by testing and
+ clearing new 'alive' member. Remove the setting of
+ record_at_most_one_child for the !WNOHANG case.
+ (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
+ now does this internally.
+ (handle_child_signal): Let record_child_status_change do all
+ the work, since we do not want to reap all exited child processes,
+ only the child processes that Emacs itself created.
+ * process.h (Lisp_Process): New boolean member 'alive'.

+ * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
+ between bpos_covered and bpos_max. This fixes cursor display when
+ several display strings follow each other.
+
+ * .gdbinit (pgx): If the glyph's object is a string, display the
+ pointer to string data, rather than the value of the string object
+ itself (which barfs under CHECK_LISP_OBJECT_TYPE).
