[Qemu-devel] Insta-segfault! i386-linux-user

[Thayne Harbaugh]

Has anyone seen an insta-segfault with i386-linux-user qemu?  I've
compiled qemu-0.9.0 as well as qemu-cvs (2007-09-18) with gcc-3.4 and
-fno-strict-aliasing on an amd64 and I get this:

./i386-linux-user/qemu-i386 --help
Segmentation fault

>From GDB:

Program received signal SIGSEGV, Segmentation fault.

Nice NULL frame there - and it's before main() is reached.
