How does one figure out what the error was? I built everything and ran the unit tests, and there were no errors, nor were there with most of the CI builds/tests. But here, it says one of the fuzz tests (only when compiling with GCC v6) had a segmentation fault, but I don't even know what it was testing:

        Start 2907: fuzz.MINIMIZED/fc5434a62691cb7f3ba4e327d713bb84024ce265
2907/3370 Test #2907: fuzz.MINIMIZED/fc5434a62691cb7f3ba4e327d713bb84024ce265 ...................***Exception: SegFault  0.27 sec

[...]

99% tests passed, 1 tests failed out of 3370

Total Test time (real) = 451.70 sec

The following tests FAILED:
	2907 - fuzz.MINIMIZED/fc5434a62691cb7f3ba4e327d713bb84024ce265 (SEGFAULT)
Errors while running CTest

@lefticus I know you've been busy with your various C++ conference presentations... (-; Any tips on how to figure out what the above fuzz-testing error was? Thanks.

I have been busy, but I'm just going to go ahead and merge this and sort out the details of why that test was failing. It was a test that was automatically created with a fuzzer, so if the nature of the test changes because of correctness - that's OK.
