Looks like a spurious memory corruption problem.

If your problem is repeatable you may try to run ctest (for the failing test)
from within valgrind using --trace-children.

Something like

valgrind --trace-children --time-stamp=yes  --log-file=ctest-trace.txt
 ctest <appropriate argument>

may be you can catch something?
