Yes, I did this and it crashes exactly where I pointed out in my first post:
(gdb) run
Starting program: /home/sszy/development/armadeus-u-boot/u-boot -c host\
bind\ 0\ /tftproot/rootfs.raw\;\ host\ load\ hostfs\ -\ 0\
/tftproot/opos6ul-linux.bin\;\ ext4write\ host\ 0:2\ 0\
/boot/opos6ul-linux.bin\ \$\{filesize\}
