[HackingRepo]

Hi, uutils mainteners

printfr panic when using too smal negative numbers. as we confirmed

relunsec@relunsec:~/software/coreutils/target/debug$ ./printf "Padding: |%-101727s|\n" "abc"

thread 'main' (45664) panicked at src/uucore/src/lib/features/format/spec.rs:559:9:
Formatting argument out of range
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Padding: |abc

note in the time the panic in line 559 which different code, so not duplicate, the previous one yes
