On my system what happened was very random.  Some symptoms:

- ibus-libpinyin sometimes crashed after inputting one or two keys
- epiphany (GNOME browser) sometimes crashed on startup
- GCC sometimes hung building itself (on the insn-match-*.cc files)
- "make" sometimes segfaulted
- GDB sometimes segfaulted (detected when trying to analysis the core
dump from above)

Some "interesting" aspect of them:

- once a symptom showed up, it did kept reproducing until reboot
- when GDB happened to work, it showed that ibus-libpinyin, epiphany,
and make all crashed in their (different) hashtable implementations

I tried to bisect but failed because it was too random.  After applying
the patch I rebooted 10 times and there's no longer such a symptom (at
least yet).  This I'm 90% sure what hit is the same issue.
