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... :)
