[svn-r22122] Issue 7785 - Writing or reading many small chunks ran out of memory and caused seg fault. I added checks in two places to make sure the library returns error stack
when it fails to allocate memory. I didn't add any test to the test suite since there is no good way to test it. But I tested and verified the error stack by hand. Tested on jam, koala, ostrich.
