I used the debugger to bring some light into it.
The crash is at lastfiles.insert:
========================
void LastFilesSection::add(FileName const & file)
{
// If file already exist, delete it and reinsert at front.
LastFiles::iterator it = find(lastfiles.begin(), lastfiles.end(), file);
if (it != lastfiles.end())
lastfiles.erase(it);
lastfiles.insert(lastfiles.begin(), file);
if (lastfiles.size() > num_lastfiles)
lastfiles.pop_back();
}
========================
This is the implementation of vector::insert()
========================
template <class _Tp, class _Allocator>
typename vector<_Tp, _Allocator>::iterator
vector<_Tp, _Allocator>::insert(const_iterator __position, const_reference __x)
{
#if _LIBCPP_DEBUG_LEVEL >= 2
_LIBCPP_ASSERT(__get_const_db()->__find_c_from_i(&__position) == this,
"vector::insert(iterator, x) called with an iterator not"
" referring to this vector");
#endif
pointer __p = this->__begin_ + (__position - begin());
if (this->__end_ < this->__end_cap())
{
__RAII_IncreaseAnnotator __annotator(*this);
if (__p == this->__end_)
{
__alloc_traits::construct(this->__alloc(),
_VSTD::__to_raw_pointer(this->__end_),
__x);
++this->__end_;
}
else
{
__move_range(__p, this->__end_, __p + 1);
const_pointer __xr = pointer_traits<const_pointer>::pointer_to(__x);
if (__p <= __xr && __xr < this->__end_)
++__xr;
*__p = *__xr; <====== here it crashes
}
__annotator.__done();
}
else
{
allocator_type& __a = this->__alloc();
__split_buffer<value_type, allocator_type&> __v(__recommend(size() +
1), __p - this->__begin_, __a);
__v.push_back(__x);
__p = __swap_out_circular_buffer(__v, __p);
}
return __make_iter(__p);
}
========================
And this is the __move_range allocator:
========================
template <class _Tp, class _Allocator>
void
vector<_Tp, _Allocator>::__move_range(pointer __from_s, pointer __from_e,
pointer __to)
{
pointer __old_last = this->__end_;
difference_type __n = __old_last - __to;
for (pointer __i = __from_s + __n; __i < __from_e; ++__i, ++this->__end_)
__alloc_traits::construct(this->__alloc(),
_VSTD::__to_raw_pointer(this->__end_),
_VSTD::move(*__i));
_VSTD::move_backward(__from_s, __from_s + __n, __old_last);
}
========================
Here the member d is a nullptr:
========================
FileName & FileName::operator=(FileName const & rhs)
{
if (&rhs == this)
return *this;
d->name = rhs.d->name;
d->fi = rhs.d->fi;
return *this;
}
========================
I don’t know if this is helpful.
