I've been trying to run with Xcode 7's address sanitizer, and I'm having trouble understanding the problem flagged here. It looks to me like a problem inside of the newly annotated `vector::__swap_out_circular_buffer` at the end of a `push_back` operation.

It's dying inside the allocation on line 4 just after `__annotate_delete()`.

vector<_Tp, _Allocator>::__swap_out_circular_buffer(__split_buffer<value_type, allocator_type&>& __v)
{
    __annotate_delete();
    __alloc_traits::__construct_backward(this->__alloc(), this->__begin_, this->__end_, __v.__begin_);
    _VSTD::swap(this->__begin_, __v.__begin_);
    _VSTD::swap(this->__end_, __v.__end_);
    _VSTD::swap(this->__end_cap(), __v.__end_cap());
    __v.__first_ = __v.__begin_;
    __annotate_new(size());
    __invalidate_all_iterators();
}

Here's the full error report.

AddressSanitizer debugger support is active. Memory error breakpoint has been installed and you can now use the 'memory history' command.

Please, file a bug report, ideally, with instructions on how we can reproduce this.

I was having a similar problem with the std::vector(size_type size) constructor getting a false heap overflow.

Unfortunately in a small test application, the problem didn't occur, so I can't send in a report to Apple.

To work around the problem, I set the optimization level to 1 by passing "-O1" to the compiler. I noticed this in a lot of ASan examples. When I did this, the false overflow reports with std::vector went away.

Hmm, I have a similar issue I cannot get rid of even when setting opti-level to -01. This problem gets triggered pretty early in my app's code rendering ASAN rather useless... bummer.

yohst,

The problem you are reporting is unrelated. It's an overflow in memcpy. If your code does not call memcpy, please report the problem to the owners of the framework you are calling. Until the bug is fixed, you can work around this issue by suppressing errors coming from external libraries:

.... it goes on. Am I correct in reading these stack traces that this is a bug in the address sanitizer itself? Just updated to Xcode 7 today. Bummer.
