Therefore omitting dsymutil will narrow the search for the problem(s).

What version of clang?  I showed that I used clang-6.0.1-2.fc28.x86_64.
Also, the default on Mac is to use addresses greater than (1ul<<32).
This catches some errors of storing an address in a 32-bit variable.
The default on Fedora is to start using addresses at 4MiB, which
saves 4 bytes of space in several important places, but in many
cases avoids noticing the problem of storing an address in 32 bits.
