我有一个使用 Boost 1.47.0 在 Windows XP SP3 中运行的 Visual Studio 2008 C++03 应用程序。

该调用boost::filesystem::create_directories( L"c:\\foo\\bar" );引发std::bad_alloc异常。

在输出窗口中，我看到一条调试堆消息：“HEAP [test.exe]: Invalid allocation size - CDCDCCDCE (exceeded 7ffdefff)”

调用堆栈显示 boost.filesystem 在 Microsoft 标准库文件 xlocale 第 309 行中创建新的语言环境和最后可见的代码行。

有人可以建议如何解决这个问题吗？

编辑我更新为提升 1.50.0。问题依然存在。

这似乎是微软在运行 DEBUG 构建时的一个已知错误。std::locale报告于 2012 年 6 月。

The message you get regarding memory address CDCDCDCE implies accessing deleted memory, as this bug describes.

There is no solution currently described in Microsoft's site, but I would suggest trying a different facet by changing L"c:\\foo\\bar" to "c:\\foo\\bar".

This problem smells like a mismatch in _SECURE_SCL (or maybe the somewhat related _HAS_ITERATOR_DEBUGGING - but I doubt the latter, since the call stack indicates a non-debug build). See https://stackoverflow.com/a/6104239/12711 for some info and make sure _SECURE_SCL is defined the same way in the builds for test.exe and the boost filesystem library linked in.

AFAIK, boost will use the VC default (which is _SECURE_SCL=1 even in release builds for VS2008), so if you're setting _SECURE_SCL=0 that may be the problem.
