well, as i suggested it in bugzilla, i'd need to capture information about |
12 |
the crash (probably triple fault), and the best approach would be some nested |
13 |
virtualization setup. i have no idea how to do it easily (one way would be to |
14 |
use bochs to run vmware if its vmx emulation is good enough but i guess the |
15 |
resulting speed would be unbearable). |
16 |
|
17 |
another (but still time consuming) approach would be to do a binary search on |
18 |
vmmon by stopping it at various points as it is about to launch a virtual machine, |
19 |
that would eventually narrow down the failing code too. |

that's weird, i don't think the toolchain can even produce anything but |
29 |
ELF for some time now ;). as for harm, the a.out loader has had its share |
30 |
of security vulnerabilities and has usually been disabled by security |
31 |
conscious distros such as Owl for many years now. but it's your risk&call ;). |
