Crash in Damage/Composite (bad free)
This issue keeps popping up in the context of TigerVNC's Xvnc:
I doubt it is TigerVNC specific, but is most likely a bug exposed by not having any hardware driver for Composite or Damage.
There is a patch on the Red Hat entry, but it looks more like a workaround than a fix. I would assume that
cw->damage are supposed to be in sync.
Could anyone have a look?
