That's insufficient. You need to run ef twice, once without
EF_PROTECT_BELOW, once with EF_PROTECT_BELOW=1, and I also recommend
EF_ALLOW_MALLOC_0=1, EF_FILL=85 and EF_PROTECT_FREE=1.

So your memcheck.sh is likely:

#!/bin/sh
env VAL="ef" EF_ALLOW_MALLOC_0=1 EF_FILL=85 \
    EF_PROTECT_FREE=1 EF_PROTECT_BELOW=1 \
    make check
env VAL="ef" EF_ALLOW_MALLOC_0=1 EF_FILL=85 \
    EF_PROTECT_FREE=1 make check
env VAL="valgrind --num-callers=32" make check

Feel free to commit that to the source tree into tests/
