当尝试运行我的Rails应用程序时（通过运行rake，。/ script / console或./script/server），我得到src / tcmalloc.cc：353]尝试释放无效指针或分段错误（取决于如果在REE或MRI上运行）。它一直运行到昨天，当没有特别的原因（没有安装任何新的宝石，没有更新任何包）它开始发生。我不知道什么可能导致这个问题，不知道如何找到问题的根源。 GDB输出对我来说没有多大意义：

我试图降级gcc和库使用Ruby原生扩展，完全重新编译Ruby，重新安装Gems，但问题仍然存在。
答案 0 :(得分：3)
这是由于以下tcmalloc / OS X错误：http://code.google.com/p/google-perftools/issues/detail?id=280
修复是使用C扩展中的ruby_strdup（），或完全避免strdup。
答案 1 :(得分：0)
这可能是Ruby中的错误（或可能是YAML::Syck::Node中的错误。）
在Valgrind下运行您的程序，并将生成的报告发送给Ruby开发人员（假设该bug使用最新的Ruby重现）。
Ruby试图释放的指针已经被ASCII："ysql\-ad"

我最近在Leopard上遇到了各种REE版本。似乎与REE一起提供的tcmalloc存在问题。用--no-tcmalloc重新编译ruby为我解决了。
如果你正在使用RVM，这意味着：
rvm install ree --ree-options "-c --no-tcmalloc"
