c++ - 带有 AddressSanitizer 的 std::system_error 说：“也许你正在使用 ulimit -v”

问题描述

我有一个多线程程序，它抛出一个std::system_error并且我不知道这个错误的来源，所以我尝试在启用地址清理器的调试模式下运行它。Asan 首先告诉它未能在特定地址上分配一定数量的字节，然后它报告：failed to write xxxx bytes: Perhaps you are using ulimit -v

我不明白使用 ulimit -v 是什么意思。我检查了 ulimit -a 的输出，我的虚拟内存设置为无限制。

我不知道如何跟踪这个问题以及我应该从 Asan 的报告中理解什么。下面是我的堆栈跟踪，我正在使用 bazel 进行编译和调试。
