powerpc64 10.1-STABLE context; cmake's /usr/local/bin/ctest broken but graphics/png configuration defaults use it

This works fine for me. Are you sure you don't have some weird 
configuration or hardware problem?

But in my context ctest is broken, trying to reserve 2305843009213693952 Hashtable_node<...>*'s [see #8's ...::reserve (..., __n=...) below] when _M_initialize_buckets(..., __n=100) in #9. (Note: 2305843009213693952 == 0x2000000000000000.) I have yet to figure out how that magic number is becoming involved. See below from one of the crash dumps:
