git master sources from today, on Ubuntu 21/10.
With Ubuntu clang version 15.0.2-1 there is one failure that
is not present in my g++ (Ubuntu 12.2.0-3ubuntu1) build:
28 - test-virtual-memory (SEGFAULT)
Here is a section of the "make test" output, followed by
autotest/cpp/testvirtualmem
and
gdb autotest/cpp/testvirtualmem
runs.
