Identifier has already been declared with mangled option

Version: 0.25.2 Angular: 9

Options:

identifierNamesGenerator: 'mangled',
stringArray: true,
rotateStringArray: true,
shuffleStringArray: true,
selfDefending: true,

Using it with a fairly decent sized angular project that uses multiple bundles I’m running into the following errors when using the “mangled” option:

Uncaught SyntaxError: Identifier 'a' has already been declared

I also tried the “dictionary” option with a supplied list of identifiersDictionary while the obfuscate command succeeds it still fails at runtime with a “Identifier ‘xxx’ has already been declared”. However, its intermittent some builds work while other times fails.

Using “hexadecimal” works however it has a pretty big footprint. For example, a 500Kb gz gets to about 950 gz with hexadecimal.

Anyway the “mangled” option generator can be optimized?

Will check it. Also, should update all plugins (webpack, gulp, grunt) to generate prefix for different bundles. Also, should describe it in the README.md
