[Qemu-devel] Segfault with latest rfb patch + qemu CVS

[Matthew Bloch]

Hi there,

Am trying to get the latest rfb8 patch working with the latest CVS qemu 
(from libvncserver.sf.net/qemu) but not having a lot of luck.  I made 
one modification to vnc.c which took out the reference to the SDL 
display driver which I didn't want to compile in.

The crash looks like this:

antec:/home/mattbee/builds/qemu# gdb ./i386-softmmu/qemu
(gdb) set args -vnc -k en-gb ../../hda
(gdb) run
Starting program: /home/mattbee/builds/qemu/i386-softmmu/qemu -vnc -k 
en-gb ../../hda

Any pointers appreciated at this early stage :)
