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. Tested-by: Xi Ruoyao --=20 Xi Ruoyao
