Research direction

Start with the ptx command entry point and reproduce the failure using ptx -g 99999999999 a. Trace how the -g value is parsed and compare the result with GNU ptx for an oversized value. Done means ptx reports an error instead of attempting the allocation and aborting, with a regression test covering the case.

Description

U - ptx

Hi, uutils mainteners

ptx panics when the -g option is a large number instead of erroing out like the GNU ptx

to reproduce that, i used

relunsec@relunsec:~/software/coreutils/target/debug$ ./ptx -g 99999999999 a
memory allocation of 99999999999 bytes failed
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Aborted                    (core dumped) ./ptx -g 99999999999 a
relunsec@relunsec:~/software/coreutils/target/debug$

then i compared it with GNU ptx as i see no panic when -g is a large number
