Under abnormal conditions the item_count may exceed the max
allocation size on 32-bit systems, this causes the allocated
size to overflow and become too small for the given count.
Additionally, if av_reallocp() fails its allocation, the
fragment_index_count is not correctly decremented.
Ensuring further havoc may be wrought, the error code for
read_tfra() is not checked upon return.
