This isn't as helpful because you're tracing the initdb process. The
core file would give a backtrace of the postgres process, which is what
is actually crashing.

This is the result of postgres crashing and thus initdb being unable to
write any more data to it.
I think you should try harder to generate the core file. Maybe you have
too low an "ulimit -c" setting?
