MacOS 使用 Asan 编译 C++报警告malloc: nano zone abandoned due to inability to reserve vm space.的解决方案

问题

clang(llvm) 编译 c++程序, 带内存问题检查工具选项-fsanitize=address -fsanitize=undefined 之后出现:

malloc: nano zone abandoned due to inability to reserve vm space.

解决

vi ~/.zshrc
# 加入:
export MallocNanoZone=0
source ~/.zshrc
