Description

The attached .aux file has a "loop" in the HFAEntry's in the file which causes GDAL to hang building an endless list of HFAEntries.

I have prepared a patch and applied to trunk as r12390. This patch really only addresses the case of a loop within one set of sibling HFAEntries as occurs in this .aux file. A parent/child or other more distance loop could still result in a similar hang but broader loop testing could get expensive. I'm really not clear how a file with this particular corruption ever got created.

Patch also back applied in 1.4 branch (r12391) and 1.4-esri branch (r12392).

added regression test (r12393) in trunk.
