我有以下簡單的python代碼，它使用libclang python綁定遍歷AST，不幸的是它崩潰與分段錯誤。 我使用python2.7，並嘗試了所有的以下鐺版本3.8，3.9，4.0，5.0，6.0（當然還有用於每個版本的權利蟒蛇鐺綁定）python-clang崩潰與分段錯誤
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)

我正在上從GitHub比特幣的源代碼的Python代碼，這回溯是文件的src /比特幣，cli.cpp
爲什麼它崩潰什麼想法？ 謝謝，Sagi
使用最新libclang.so時，它也發生了：clang.cindex.Config.set_library_file（'/ usr/lib目錄/ LLVM-6.0/lib目錄/ libclang 。所以'） – sagi
