Description

Hi, uutils mainteners

as our test confirms when we use ulimit, sort panics

relunsec@relunsec:~/software/coreutils/target/debug$ ./sort /dev/full
memory allocation of 1207959552 bytes failed
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Aborted                    (core dumped) ./sort /dev/full

while the gnu one

relunsec@relunsec:~/software/coreutils/target/debug$ gnusort /dev/full
gnusort: memory exhausted
relunsec@relunsec:~/software/coreutils/target/debug$ 

as i see it says memory exhausted, however the uu one panics when ulimit

Research direction

Reproduce the failure with the reported ulimit, ./sort /dev/full, and GNU sort for comparison. Then locate the sort entry point and its memory-error handling; done means the Rust implementation reports memory exhaustion and exits without panicking under the same limit.
