Here is the stacktrace from gdb on 5.2 beta2. As I said before, this
does not segv at least I did not wait that long to see and I have let it
run for 5+mins in the past with it using 100% cpu. The numbers for x1
and x2 in the call to imageScanline() look suspect, but I'm not familiar
with this code.
(gdb) bt
