It's this code in
http://svn.opensuse.org/viewvc/yast/trunk/perl-bindings/pluglib-bindings/swig/stl/string.i?revision=57030&view=markup#l30
%typemap(in) std::string* (std::string temp), std::string& (std::string temp),
const std::string* (std::string temp), const std::string& (std::string
temp)
{
SV *sv;
if (!SvROK($input) || !(sv = (SV*)SvRV($input)) || !SvPOK(sv) )
SWIG_croak("Type error in argument $argnum of $symname. Expected a
REFERENCE to STRING.\n");
STRLEN len;
const char *ptr = SvPV(sv, len);
if (!ptr)
SWIG_croak("Undefined variable in argument $argnum of $symname.");
temp.assign(ptr, len);
$1 = &temp;
}
Now, the typemap makes a copy of the referenced string anyway, so there is no
point in requiring a reference instead of a plain string. I wonder how it can
work in the other cases:
$ grep "REFERENCE to STRING" LibStorage_wrap.cc | wc -l
