One thing you could try is identifying which revision causes the
problem. I'm guessing that r1072301 will PASS, it would be good to
know which is the first revision to FAIL.

The crash might involve the caching's pointer twiddling code, so I
suppose it might be a signed integer overflow bug. Perhaps compiling
with EXTRA_CFLAGS='-O2 -fno-strict-overflow' would PASS?

It's difficult because I can't reproduce it.
