Haiyan,

When reporting crashes within gdb it is also helpful to do a "where" command
so we can see the whole call stack.

This seems like it might be a bug in GDAL.  I would encourage you to report
it in the MapServer Bugzilla and ensure it is assigned to me.  You will need
to provide a dataset (ideally a smallish raster file that also demonstrates
the problem). Also, ensure you provide details on the version of GDAL you
are using.

Best regards,
