Done. Ivan has effectively found the problem: you was invoking a table iterator without having the table bounded to a variable. With this, the table died shortly after iterator initialization, so removing the input buffers. As a consequence of this, when the iterator object (who meanwhile was well and alive) tried to write in the table input buffer, the later didn't exist and hence, provoking the crash. In any case, the workaround is correct (in fact, it will go in the forthcoming PyTables 1.3.1), so you can use it without problems. However, Ivan didn't liked the present solution of sharing the input buffers between Table and Row objects, so we ended implementing another solution in which a Row will always have its own input buffers (if needed) and Table will have the output buffer (as there is no way to have different output buffers, then Table is the logical place to put it). In fact, this separation of buffers has allowed an important simplification of the buffering code, and we hope that this will bring improved stability for the whole beast. This new code will appear in future PyTables 1.4, but if anybody wants to contribute checking it, you can download the SVN trunk and have it a try.
