[Qemu-devel] Segmentation fault in qemu-system-sparc

[Gabriel Southern]

Hi,

I am getting a segmentation fault when I run qemu-system-sparc.  I
think it is caused by a change after
6c7f4b47f778258493744a690bfc8dbbb7d21f69 on 5/13 because if I reset to
that commit the segmentation fault does not occur.  The segmentation
fault occurs during OS boot when the network interface is being
configured:

Setting up networking....
Configuring network interfaces...Segmentation fault

The last function call I can see with gdb is:

#1  0x0000000000426fb7 in pcnet_init () at qemu/hw/pcnet.c:876
876	        s->phys_mem_read(s->dma_opaque, PHYSADDR(s,CSR_IADR(s)),

Also my host system is CentOS 5.2 x86_64.  If anyone knows what the
problem is or has questions/suggestions for fixing it please let me
know.

Thanks,

-Gabriel

I bisected this to 9d07d7579bcaf01e05c511c63d091ed2ac310091 "PCI
network qdev conversion", but I don't see any problems with the
pcnet.c part of the commit. Paul?
