Closing in favor of https://github.com/llvm/llvm-project/pull/175097. Generally we don't expect any part of the driver to be free of sandbox violations. The new PR disables the sandbox for the entirety of the driver usage within the sandboxed frontend, instead of just fixing the single offending function call and hoping other parts of the driver don't trigger more violations.
