Hi,

I have a reproducable bug, but involving a rather complex setup, before
attempting to track this down, I would like to know if this is already
known.

Versions note for the host system:
> uname -a
Linux 2.4.21-37.EL.cernsmp #1 SMP i686 i686 i386 GNU/Linux
It's an SLC3 on a PIV computer.
qemu is compiled from a recent CVS checkout.

The target system is x86_64 running some (somewhat) misconfigured SLC3
(RHE3 derivates). Missconfigurations can comes from the fact that I
couldnt boot the slc3 installer from qemu and that I installed
it"manually" and have a few stranges things (dhcp doesnt work, wget
fails strangely). I know I should first clarify that, but until now,
this wasnt much a problem to me: it was working enough for what I wanted.

Anyway, when trying to compile some java code using ant (in the
blackdown x86_64 JVM), qemu crashed:

$ gdb /usr/local/src/ypatois/qemu/cvs/qemu/x86_64-softmmu/qemu-system-x86_64
set ARGS=-m 256 -net user -net nic -redir tcp:2200::22 -nographic -hda
hdb.img -hdc hdc.img
r
[...]
address@hidden edg-java-security]$ ant compile

Program received signal SIGSEGV, Segmentation fault.

I dont think this report helps a lot, unless what I'm talking about is
already know.
If not, how could I improve it to help the debugging?

Thanks.

        Yannick
