Im trying to fix a bug in a BView derived class which is causing a crash
whenever the Draw() method is called for a second or more time. It works
OK the first time (when the object is first created) but subsequent
calls via Invalidate() cause a crash.
In such cases, it would be tremendously helpful to see a stack trace of
the crashed thread. You can either use gdb for this, or (sometimes it
has problems getting a correct trace), paste the stack trace that
appears in the syslog when that happens.
One possible reason for a crash would be that something trashes some
memory outside of draw.
