[Qemu-devel] [sparc64] qemu crashes after the "OpenBIOS for Sparc64" banner is printed

[Jakub Jermar <jakub@jermar.eu>]

Hi,

when I build qemu-system-sparc64 from trunk and attempt to
boot the HelenOS iso image, I immediately get segmentation fault.
Below is the output from a gdb session, show the place of
crash:

OpenBIOS for Sparc64

Program received signal SIGSEGV, Segmentation fault.

Since I get this error so early, I think this is a generic issue.
Anyone else has seen something similar?

I built qemu using gcc-3.3. The arguments I used to run qemu:
-cdrom image.iso -m 512 -boot d -nographic

Please, respond to me directly as I am not subscribed to the list.

Cheers,
