我有以下简单的python代码,它使用libclang python绑定遍历AST,不幸的是它崩溃与分段错误。 我使用python2.7,并尝试了所有的以下铛版本3.8,3.9,4.0,5.0,6.0(当然还有用于每个版本的权利蟒蛇铛绑定)python-clang崩溃与分段错误

import clang.cindex 

def traverse(node): 
    print("%-42s %-20s %-10s %-6s %s" % (node.kind, node.spelling, node.type.spelling, node.location.line, node.mangled_name)) 
    for child in node.get_children(): 
     traverse(child) 

clang.cindex.Config.set_library_file('/usr/lib/llvm-3.8/lib/libclang.so') 
index = clang.cindex.Index.create() 
tu = index.parse(sys.argv[1], args=['-Werror']) 
traverse(tu.cursor)

我正在上从GitHub比特币的源代码的Python代码,这回溯是文件的src /比特币,cli.cpp

为什么它崩溃什么想法? 谢谢,Sagi

使用最新libclang.so时,它也发生了:clang.cindex.Config.set_library_file('/ usr/lib目录/ LLVM-6.0/lib目录/ libclang 。所以') – sagi

我发现node.mangled_name导致崩溃。
