printf crashes with ValueError when integers are large #2107

Open ale5000-git opened 6 days ago

Oils 0.23.0 installed with brew install --quiet oils-for-unix.

Currently this works: printf '%u\n' '9223372036854775807' but this: printf '%u\n' '18446744073709551615' instead give this error: libc++abi: terminating due to uncaught exception of type ValueError*

I think it is better if the code check what is really requested. For "%d" and "%i" I think it should be cast to "long long", instead for "%u", "%o" and "%x" it should be cast to "unsigned long long" so that it will allow to use the full unsigned range.

Thanks for the report! I reproduced this

I fixed Oils to check bounds

Unfortunately it doesn't distinguish between signed and unsigned now, so these are errors

We're looking into:

Thanks for the report!
