我正在尝试在Nokogiri Ruby Gem中编译地址消毒剂。
使用如下地址消毒剂编译libxml2和libxslt:
./configure CFLAGS="-fsanitize=address,undefined -Wformat -Werror=format-security -Werror=array-bounds -g" CXXFLAGS="-fsanitize=address,undefined -Wformat -Werror=format-security -Werror=array-bounds -g" LDFLAGS="-fsanitize=address,undefined" CC="clang" CXX="clang++"
安装了这样的宝石:
sudo gem install nokogiri --version 1.8.0 -- --use-system-libraries --with-xml2-include=/home/user/Downloads/libxml2-2.9.3/include/ --with-xml2-lib=/usr/local/lib/ --with-cflags=\"-fsanitize=address\" --with-ldflags=\"-fsanitize=address -lasan -lubsan\" --with-xslt-include=/home/user/Downloads/libxslt-1.1.28/ --with-xslt-lib=/usr/local/lib/
但是,当我使用nokogiri运行示例ruby脚本时
脚本.rb
#!/usr/bin/ruby
require 'nokogiri'
doc = File.open("sample.xml") { |f| Nokogiri::XML(f) }
我收到这个消息:
./script.rb
==30473==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.
当我进行预加载时:

我需要用地址消毒剂来构建Ruby吗?不幸的是失败了…
cd ruby-2.3.0
./configure --disable-shared CFLAGS="-fsanitize=address -ggdb" CXXFLAGS="-fsanitize=address -ggdb"
make
编译时中断,显示内存泄漏:/
如何正确启用Ruby宝石上Ruby中的地址消毒剂?
谢谢,

如@yugr建议的,尝试传递“undefined”,但没有帮助:
sudo gem install nokogiri --version 1.8.0 -- --use-system-libraries --with-xml2-include=/home/user/Downloads/libxml2-2.9.3/include/ --with-xml2-lib=/usr/local/lib/ --with-cflags=\"-fsanitize=address,undefined\" --with-ldflags=\"-fsanitize=address,undefined -lasan -lubsan\" --with-xslt-include=/home/user/Downloads/libxslt-1.1.28/
Building native extensions with: '--use-system-libraries --with-xml2-include=/home/user/Downloads/libxml2-2.9.3/include/ --with-xml2-lib=/usr/local/lib/ --with-cflags="-fsanitize=address,undefined" --with-ldflags="-fsanitize=address,undefined -lasan -lubsan" --with-xslt-include=/home/user/Downloads/libxslt-1.1.28/'
This could take a while...

用asan成功地编译了ruby、libxml2、libxst和nokogiri,但是当我运行它时,我仍然得到:
