Just to close the loop here, it turns out that this was caused by some
EDB-installed software, not macOS itself. The software in question
wasn't expected to cause this to happen, but did anyway.

We also discovered that core dumps weren't *completely* disabled. They
still occurred for segmentation faults, but not for abort traps.

So, if anyone's having a similar problem, check with your IT
department or try with a fresh OS install before blaming Apple. :-)
