Subject: Segfault with from_to
Download (untitled) / with headers

The following code snippet causes a core dump or probably an internal perl panic: panic: sv_setpvn called with negative strlen at /usr/local/lib/perl5/5.8.0/i686-linux/ line 184. use Encode qw(from_to); $value = bless {}, 'Bla'; Encode::from_to($value, "utf8", "iso-8859-1", Encode::FB_QUIET); It seems to me that using SvEND causes this fatal error. For non PV scalars, SvEND has no meaning. So fixes could be: * all encode methods could croak for scalars not containing a PV (or for scalars which do not contain a PV after applying SvPV on them) or * check whether the scalar has a PV and use SvEND, otherwise fallback to an equivalent method to get the end of the string: e = s + slen (?)
