But we actually have 2 entries.
It should not break.
(gdb) p args
$32 = {_vptr.NCVector = 0xfffff7f8a020 <vtable for
OpenSP::NCVector<OpenSP::Owner<OpenJade_DSSSL::Expression> >+16>, size_ = 2,
ptr_ = 0xaaaaab46eae0, alloc_ = 2}
(gdb) p *(args.ptr_+0)$33 = {_vptr.Owner = 0xfffff7f8a040 <vtable for
OpenSP::Owner<OpenJade_DSSSL::Expression>+16>, p_ = 0xaaaaab46f9f0}
(gdb) p *(args.ptr_+1)
$34 = {_vptr.Owner = 0xfffff7f8a040 <vtable for
OpenSP::Owner<OpenJade_DSSSL::Expression>+16>, p_ = 0x0}
(gdb) p *(args.ptr_+2)
$35 = {_vptr.Owner = 0x6c00000063, p_ = 0x1d1}
So resize should be called with argument n=1
1004 args.resize(args.size() - 1);
(gdb) p args.size()
$36 = 2
But instead:
#0 OpenSP::NCVector<OpenSP::Owner<OpenJade_DSSSL::Expression> >::resize
(this=0xffffffffe0c8, n=2) at /usr/include/OpenSP/Vector.h:27
That makes the pointer calculation go too far as +2 is outside the
vector.
