Since the tinderboxes for stable/9 are green, it is most likely your =
machine has a hardware problem.  You should at least run two or three =
full passes of memtest on your machine: this type of error typically =
occurs when data in RAM gets corrupted.

If you can't find any hardware problems, you could try to switch off =
building clang, using WITHOUT_CLANG in your src.conf.  However, if your =
hardware cannot be trusted, all bets are off... :)
