I have a Sunblade 100 running woody and I get a bus error too.

If I use gdb:
Program received signal SIGBUS, Bus error.
0x0001a240 in sysinfo () at sysinfo.c:87
87Statio    sprintf(message, _("ProductType: %lu"),
HardConf->ProductType);
(gdb) print &HardConf->ProductType
$1 =3D (long unsigned int *) 0x7b4ca

Unfortunately, 0x7b4ca is not aligned on a 4-byte boundary, thus the
bus error when trying to access HardConf->ProductType.

Two things that I do not understand:

1. I thought that gcc automatically aligns elements of structs if the
architecture of the machine requires it???

2. Why doesn't gdb give a Bus error if I go:
(gdb) print HardConf->ProductType
$2 =3D 0
???
