python铿锵崩溃，出现分段错误

我有以下简单的python代码，它使用libclang python绑定遍历AST，不幸的是，它因分段错误而崩溃。 我使用的是python2.7，并尝试了以下所有的clang版本3.8、3.9、4.0、5.0、6.0（当然，每个版本都使用了正确的python clang绑定）

我正在github的比特币源代码上运行python代码，此回溯用于文件src/bitcoin-cli.cpp

知道它为什么会崩溃吗？

谢谢，Sagi

我发现node.mangled_name导致了崩溃。

这看起来像是一个bug，正在这里跟踪：

使用最新的libclang.so:clang.cindex.Config.set_library_文件（'/usr/lib/llvm-6.0/lib/libclang.so'）仍然是libclang 7的问题。
