 A string table is allowed to reference strings multiple times
 (maybe not possible for symbol names) and also to reference
 substrings (so names like 'bar\0' and 'foobar\0' may overlap).
 
 No idea if a compiler or linker would create such a thing. But
 if that is true, you need to iterate twice over the symbols
 to determine the target size and to copy the strings.
