Hello Simon,
using sandbox_defconfig on origin/master:
Hit any key to stop autoboot: 0 => exception sigsegv
Segmentation violation pc = 0x55d3566d04f9, pc_reloc = 0x554f9

Here the SIGSEGV is correctly handled by the sandbox.
On origin/next:
=> exception sigsegv
Segmentation violation pc = 0x5567966da96b, pc_reloc = 0x5567866da96b
Writing sandbox state Segmentation fault $
The same problem is visible when executing the poweroff command.
=> poweroff poweroff ... Segmentation fault $

b308d9fd18fa sandbox: Avoid using malloc() for system state
The segmentation fault occurs when os_exit() calls dm_uninit(). The value of gd is invalid at this point.
Can you please check this patch?

Also, is there no test covering the above?
