obfuscator: An error occurred while handling BlockStatementControlFlowFlatteningNode #99

index.txt 清理死代码... 扁平化还原: _0x4924e0[_0x3fb2a9]就报错 for (let i = 0; i < pre_path.node.declarations.length; ++i) { ^ TypeError: Cannot read properties of undefined (reading 'length')

已修复。

Note:

在查找BlockStatementControlFlowFlatteningNode的variableDeclarationNode时使用了getAllPrevSiblings方法获取上面的节点。当获取到多余的节点时，由于未验证节点类型导致出现错误。
