+

+ As as example of where we might do this, some object formats
+ use string tables for which the first <<sizeof(long)>> bytes of the
+ table contain the size of the table itself, including the size bytes.
+ If an application tries to read what it thinks is one of these
+ string tables, without some way to validate the size, and for
+ some reason the size is wrong (byte swapping error, wrong location
+ for the string table, etc.), the only clue is likely to be a read
+ error when it tries to read the table, or a "virtual memory
+ exhausted" error when it tries to allocate 15 bazillon bytes

+ Copy private BFD information from the BFD @var{ibfd} to the
+ the BFD @var{obfd}. Return <<true>> on success, <<false>> on error.
+ Possible error returns are:
+
+ o <<bfd_error_no_memory>> -
+ Not enough memory exists to create private data for @var{obfd}.
