[SOLVED] busybox upgrade fails

[replabrobin]

I'm trying to update my ancient sheeva $this->bbcode_second_pass_code('', 'Linux delilah 3.19.0-1-ARCH #1 PREEMPT Mon Feb 9 21:55:44 MST 2015 armv5tel GNU/Linux
') and get this error
$this->bbcode_second_pass_code('', ' 1/45) upgrading busybox [----------------------] 100%
/tmp/alpm_dj2gwX/.INSTALL: line 11: 12982 Segmentation fault (core dumped) busybox rm -rf tmp/busybox.upgrade
error: command failed to execute correctly
')

the pacman upgrade continued and after reboot it seems the busybox update went through $this->bbcode_second_pass_code('', '# pacman -Qs busybox
local/busybox 1.23.1-2
Utilities for rescue and embedded systems
local/mkinitcpio-busybox 1.21.1-2
base initramfs tools
')

should I worry about the partial failure?

Edit: busybox-1.23.1-3.1 seems to work fine.

Install busybox again to be sure.

It seems consistent

If I run that command post install I see this
$this->bbcode_second_pass_code('', 'root@delilah:/
# busybox stat -c %a usr/bin/busybox >tmp/busybox.upgrade/busybox.upgrade.script
Segmentation fault (core dumped)
')

It seems the command is failing and in fact it's the busybox stat that fails
$this->bbcode_second_pass_code('', 'root@delilah:/
# busybox stat
Segmentation fault (core dumped)')

there is a separate stat command fro coreutils and that seems fine$this->bbcode_second_pass_code('', 'root@delilah:/
# stat -c %a /tmp/busybox.upgrade/busybox.upgrade.script
644')

The latest busybox-1.23.1-3 for arm5 seems even more broken

$this->bbcode_second_pass_code('', '/tmp/alpm_w9XxmB/.INSTALL: line 8: 29743 Segmentation fault (core dumped) busybox stat -c %a usr/bin/busybox > ${_tmp_dir}/busybox.upgrade.script

$this->bbcode_second_pass_code('', '# file /bin/busybox
/bin/busybox: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, stripped')

executing any command eg busybox ls causes a segfault. I tried gdb on one of the coredumps in var/lib/systemd/coredump/, but couldn't seem to decompress it with xz or lz4 (it has .lz4 extension). gdb certainly doesn't know what to do with them. I have excuted ulimit -c unlimited so am now stuck.

[replabrobin]

Read up on new coredumps etc etc coredumpctl gdb 433 (one of my tests)

$this->bbcode_second_pass_code('', 'Type "apropos word" to search for commands related to "word"...

Edit:I tried building my own version of the package with debug on in the makepkg.conf settings; after that I see this sort of backtrace
$this->bbcode_second_pass_code('', 'warning: core file may not match specified executable file.

_libc_start_main seems to be in the musl libc somewhere.

for what it's worth the busybox in mkinitcpio-busybox 1.21.1-2 seems fine
$this->bbcode_second_pass_code('', 'robin@delilah:~
$ /lib/initcpio/busybox ls
ORIG bin devel scripts tmp vim_backups')
