The call to fixup_symbol_section() (which is one line before the line
indicated above) should be setting section to the section associated
with the minimal symbol.  I think we need to find out why
fixup_symbol_section() is failing to do this.  (Obviously, it could be
failing if if fails to locate the minimal symbol.  If this is the
case, we need to find out if symbol simply doesn't exist in the minimal
symbol table or if it's a demangling problem...  Or possibly there's
another reason why the symbol wouldn't be found.)
