[Qemu-devel] sparc64-linux-user Segmentation fault

[Artyom Tarasenko]

Trying to run linux-user-test-0.3 from qemu.org. The programs produce
the expected output but always end up with a segmentation fault:

$ sparc64-linux-user/qemu-sparc64 ../linux-user-test-0.3/sparc64/busybox
BusyBox v1.6.1 (2007-10-20 10:22:43 EEST) multi-call binary
Copyright (C) 1998-2006  Erik Andersen, Rob Landley, and others.
Licensed under GPLv2.  See source distribution for full notice.

Usage: busybox [function] [arguments]...
   or: [function] [arguments]...

        BusyBox is a multi-call binary that combines many common Unix
        utilities into a single executable.  Most people will create a
        link to busybox for each function they wish to use and BusyBox
        will act like whatever it was invoked as!

Currently defined functions:
        echo, expr, ls

Is that a bad test or a qemu bug? The host runs Linux x86_64.
