[Qemu-devel] qemu segfault while booting with "-isa"

[Qemu-devel] qemu segfault while booting with "-isa"

I was trying to install GNU/Hurd
(which works only with the "-isa" option, I don't know why, it may be
related to GNU/Hurd)

But I can't boot the debian "install-cd" : qemu segfault when trying to
start the linux kernel.
When I start from gdb, I can see "Uncompressing Linux... Ok, booting the
kernel." This is the last message before the segfault.

Without "-isa", all is working fine, but qemu should never segfault (I
think...)

Note : I was using debian-K8-hurd-i386-mini.iso

It worked for me...

Which versions of qemu, gcc, binutils and glibc did you use?

qemu : 0.7.0 (gentoo's one)

gcc : 3.4.3-20050110 (Gentoo Linux 3.4.3.20050110-r2,
ssp-3.4.3.20050110-0, pie-8.7.7)

binutils : i686-pc-linux-gnu-2.15.92.0.2

glibc : 2.3.5

Command line : /usr/bin/qemu -isa -cdrom debian-K8-hurd-i386-mini.iso

Ok, I can reproduce that.
qemu shouldn't segfault whatever the guest OS is doing, so someone should
have a look at that.  Perhaps I can do that during the next days.

I used qemu-HEAD and the latest official versions (i.e. no patches) of
gcc, binutils and glibc.
