Also, before you spend a lot of time chasing this, make sure it's
not a mirage. Reset your source tree fully with "git clean -dfxq"
then configure, make, make install; then see if problem still exists.
If it does, the PG community's accumulated wisdom about getting stack
traces is here:
https://wiki.postgresql.org/wiki/Generating_a_stack_trace_of_a_PostgreSQL_backend
Note that the "child process exited" message you show implies that the
failure was not in initdb itself, but in the single-user postgres
backend process that it spawns. This means that any core file would
have been dumped into the created data directory, so you would have
to use initdb's --no-clean option to prevent it from being removed
immediately.
Also, if you are using a systemd-based Linux distribution, you may
have to negotiate with systemd-coredump to get back any core dump
at all. "man 5 core" can be helpful reading here (personally
I just disable systemd-coredump per the directions shown there).
