每当我在 Release 中构建代码时，它都会编译并运行良好。但是，当我切换到调试时，我得到了一些我似乎无法弄清楚的错误。

我同时使用 SWIFT 和 OPCODE 库。我在 C++-> 代码生成中的“运行时库”字段对于所有 3 个项目（我的主项目、swift、操作码）都相同。我已尝试将它们全部设置为 \MT 并全部设置为 \MD 以进行调试模式，但都不起作用。实际上，当它在 Release 中成功构建时，我必须将 Opcode 和我的活动项目设置为 \MD（swift 可以是 \md 或 \mt 并且它仍然可以构建）。我不太了解用于链接的运行时库...所以如果这是问题所在，您可以尝试明确吗？
我也去寻找_ITERATOR_DEBUG_LEVEL，但找不到。我应该在哪里更改它？我在源代码的任何地方都找不到它。我没有在项目属性中看到它，但完全有可能我只是没有在属性中找到正确的位置。
显然，人们在字符集不匹配时也遇到过类似的错误。我已经尝试将它们全部设置为 multi 并全部设置为 unicode。那似乎没有任何效果。
目前，我的活动项目只有 swift.lib 作为附加依赖项。我有 opcode.dll 和 opcode_d.dll 所以我不会静态链接它们。
在 C/C++ 设置下的预处理器中，我有以下预处理器定义：
操作码：
WIN32
_DEBUG
_WINDOWS
_USRDLL
OPCODE_EXPORTS
迅速：
_DEBUG
WIN32
_LIB
LOOKUP_TABLE_5_625
活跃项目：
WIN32
_DEBUG
_CONSOLE
如果需要，我可以提供更多信息。谢谢你的帮助。
