Everything works fine except occasionally it gives a segfault when I attempt to call GDALClose on the original dataset (opened with GDALOpen).  It happens about every 1 in six times I run it.

Wendy,

No reason for this is immediately obvious, but if you are working on
Linux I would strongly encourage you to try your program under valgrind.
It is very good at identifying heap corruption, memory overwrite, post-free
memory use and similar problems.

Best regards,
