Toplevels need access to their own symbol table, and they look inside
their executable file to find it. The symbol table information is not
available if -output-obj is selected.
A regular bytecode executable file is composed of several sections:
code, data, symbols, and debug info. Currently, only the first two
are available when a C object is generated instead of a regular
executable file.
For the same reasons, you can't debug a Caml program built with
-output-obj.
Hope this helps,
