Требует ли boost :: interprocess :: windows_shared_memory какой-либо специальной инициализации при использовании изнутри DLL?

Я уже задавал вопрос надбавки между процессами и поклялся, что перестану его использовать, но, увы, я застрял и мне очень нужна эта штука для работы. Так что я все еще борюсь с этим.

У меня странный сбой при распределении, а затем сразу же уничтожаю boost::interprocess::managed_windows_shared_memory::segment_manager но это происходит только из проекта Windows DLL, который я создаю. Я пытался воспроизвести его в отдельной программе, чтобы сообщить об этом в Boost, но он не воспроизводится вне моей собственной DLL.

Это также происходит, когда я обычно создаю объект и освобождаю его в более разумное время, но здесь я пытаюсь показать, что Boost способен создавать объект, и что время не прошло, а состояние не изменилось. куча, и все же Boost не может освободить этот объект без сбоя.

Этого не происходит в отдельном примере проекта (я создал его, просто чтобы посмотреть, будет ли он), но все же никакой другой код, о котором я знаю, не выполняется в проекте, где происходит сбой.

Что действительно странно, так это то, что он падает из-за функции DLLMain, и это самое первое, что происходит в функции DLLMain — это выделение, а затем уничтожение этого объекта повышения C ++. Что-то странное в этом объекте повышения — он создает много вещей (красное дерево) и не может даже очиститься.

Код ниже почти, но не достаточно, чтобы воспроизвести проблему. Что-то не так с моей DLL, из-за которой получающиеся объекты Boost могут создавать сами себя, но они перестают работать при завершении работы:

Короче говоря, с managed_windows_shared_memoryнезависимо от того, какой объект вы создаете, он даже не может быть уничтожен чисто (без нарушений доступа) даже сразу, что я и пытаюсь показать выше, где я создаю объект при загрузке DLL и уничтожаю его при выгрузке DLL.

Вот трассировка стека. если вы понимаете это, вы, скорее всего, компилятор C ++, а не человек, но в любом случае это так:

Короче у меня

A. исключил повреждение кучи из кода, написанного мной, потому что никакой другой код еще не выполнялся в контексте этой DLL. Другие объекты могут быть созданы и освобождены, нет проблем, только этот объект Boost не может быть создан или уничтожен в этой DLL.

Б. Проект DLL компилируется с генерацией кода, установленной как «Многопоточная отладочная DLL».

C. деструктор для boost::interprocess::managed_windows_shared_memory::segment_manager всегда падает в одном и том же месте, это не случайно в любом случае. Это место mydll.dll!boost::interprocess::offset_ptr<boost::intrusive::compact_rbtree_node<...,

D. Если я переключаюсь с общей памяти Windows, в этом контексте DLL, на другой вариант, просто называемый shared_memoryзависает / тупики в get_last_bootup_time на вызов WMI. Это функция из win32_api.hpp, которая выполняет вызов функции Window WMI и пытается прочитать класс Win32_OperatingSystem имущество LastBootUpTime,

E. Я начинаю думать, что библиотеки DLL и Boost не любят друг друга по странным странным причинам, возможно, с участием CoInitializeи темная черная магия.

Как вы отлаживаете что-то такое сумасшедшее?
