memory leak in KinoSearch::Util::BitVector (v .15)
[In reply to]
|
|
Just doing a bit of digging. Would adding sv_2mortal make a difference?
PPCODE:
out_av = Kino_BitVec_to_array(bit_vec);
/* XPUSHs(sv_2mortal(newRV_noinc( (SV*)out_av ))); */
XPUSHs(sv_2mortal(newRV_noinc( (SV*)out_av )));
XSRETURN(1);
Thanks again,
Matthew
