Here's the thing -- it looks like everything assumes that the place
'scr' ends up pointing to has been already initialized somehow. Every
sourceline that I've been able to identify using
"grep vgascreen /sys/src/9/*/*"
does exactly what you've mentioned: 'scr = &vgascreen[0];' but the problem
is -- scr never gets written to, which means there's not way vgascreen could
be initialized.
Or am I missing something really obvious here ?
Thanks,
