Hi Jason,
But this still does not explain why the sequence
load, delete, load again the same file (PB.h5m, for example) fails. It must be something with the file.

(it does not fail for tree.h5m file in kd_tree_test.cpp)

reading the first time is fine. Is there something about reading the same tags (definitions) again?
