Comment 4 for bug 1264627

Changing build configuration worked. To build release, use:

opt: cmake -DBUILD_CONFIG=xtrabackup_release && make -j4
dbg: cmake -DWITH_DEBUG=ON && make -j4
val: cmake -DWITH_DEBUG=ON -DWITH_VALGRIND=1 && make -j4

I was caused by using -DBUILD_CONFIG=xtrabackup_release together -DWITH_DEBUG=ON or by using -DWITH_NDBCLUSTER=0. Either may cause the issue, or they may both cause it (to be tested later if needed).
