I do:

CFLAGS="-O0 -DRELCACHE_FORCE_RELEASE" ./configure --enable-debug \
--enable-depend --enable-cassert

I have attached regression.diffs after a "make check". The diffs don't
look trivial, and actually look quite strange to me.

It happens deterministically for me, so I assume that anyone on linux
x86-64 would see the same thing.
