It is the same, but the diff is buried in some other file,
probably regress_log_027_stream_regress.

I've only noticed the two, but I did not mount an aggressive search.
It's possible that there were failures before 1772d554b0, since I
now see that the diff is in a test case that is older than that.

Same error on two different machines makes it hard to credit hardware
glitches, if that's what you mean. I could believe a bad pointer
accessing unpredictable memory, but perhaps valgrind would catch that.
