[Qemu-devel] qemu on PPC with recent distro (was Re: qemu with recent wine?)

[Wim Vanderbauwhede]

Hi,

I'm trying to figure out why qemu-0.5.3 doesn't work on PPC with a
recent x86 distro (Mandrake 10)
Here's what I tried:

address@hidden wim]$ qemu-i386 -L /home/ARCHS/mdk_x86/
/home/ARCHS/mdk_x86/bin/pwd
qemu: uncaught target signal 11 (Segmentation fault) - exiting

address@hidden wim]$ qemu-i386 -L /home/ARCHS/mdk_x86/
/home/ARCHS/mdk_x86/bin/sh -c pwd
qemu: uncaught target signal 11 (Segmentation fault) - exiting

address@hidden wim]$ qemu-i386 -L /home/ARCHS/mdk_x86/
/home/ARCHS/mdk_x86/bin/ash.static -c pwd
/common/home/wim

So, ash.static works, all other commands result in Segmentation fault.

Here's a diff of the strace of /bin/pwd vs /bin/ash.static -c pwd
To me it doesn't make much sense, but hopefully is does to you guys.
