The loops have nothing to do with the segfault.

If you can get me a reproducer I'll work on trying to identify the segfault and
work through it.  (What I likely need is a copy of your deploy directory, and
the items from the tmp/work/<machine>/<image>)

Two ways to attempt to figure out what is going on:

1) Manually reproduce it
Note, you should be able to reproduce this outside of the build system.  The
basic steps are:

run pseudo, and setup the environment for the rootfs image creation.
run the failed script above in gdb
wait until it segfaults and report on the segfault location...


2) Capture a core...

On the command line run: ulimit -c unlimited

Run the bitbake command that fails

Look for the dumped core file, likely in tmp/work/<machine>/<image> "somewhere".
 Should be named "core.XXXXXX" where XXXXXX is a pid.

Run gdb on the core file similar to:

gdb <path>/tmp/sysroots/x86_64-linux/usr/bin/rpm.real <path>/core.XXXXXX

assuming that is successful, you should be able to type "bt" and figure out
where the crash occurred.


Again let me know if you get any reasonable results and I can further investigate.
