c++ - boost::split 算法崩溃（无法访问内存）

Question

我在提升算法中遇到崩溃

堆栈跟踪是：

在代码中用作以下函数：

boost::split(signals, name, boost::is_any_of("."), boost::token_compress_on); 
template<typename Derived>
struct predicate_facade {}; 

在上面的代码中，对于这个指针，我得到了无法访问 gdb 中的内存错误：

(gdb) p this Cannot access memory at address 0x7fffff3feff8

但它在小代码中运行良好（在 ideone 上试过）： https ://www.ideone.com/jnB037 请帮帮我。
