boost.filesystem create_directories抛出std :: bad_alloc [英] boost.filesystem create_directories throws std::bad_alloc

问题描述

我有一个使用Boost 1.47.0的Visual Studio 2008 C ++ 03应用程序，该应用程序在Windows XP SP3中运行.

I have a Visual Studio 2008 C++03 application using Boost 1.47.0 running in Windows XP SP3.

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]:无效的分配大小-CDCDCDCE(超过7ffdefff)"

In the output window, I see a debug heap message: "HEAP[test.exe]: Invalid allocation size - CDCDCDCE (exceeded 7ffdefff)"

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

The callstack shows boost.filesystem creating a new locale and last visible line of code in the Microsoft standard library file xlocale line 309.

有人可以建议如何解决此问题吗?

Can anybody suggest how to fix this issue?

EDIT (我更新为1.50.0).问题仍然存在.

EDIT I updated to boost 1.50.0. The issue remains.

推荐答案

这个问题闻起来像是_SECURE_SCL中的不匹配(或者也许是有些相关的_HAS_ITERATOR_DEBUGGING-但我怀疑后者，因为调用堆栈指示非-debug版本).有关某些信息，请参见 https://stackoverflow.com/a/6104239/12711 并确保已定义_SECURE_SCL

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将使用VC默认值(即使在VS2008的发行版中也为_SECURE_SCL=1)，因此，如果您设置_SECURE_SCL=0，可能就是问题所在.

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.
