Description
Hi, uutils mainteners
i want let you known that the uutils od, , as i tried
relunsec@relunsec:~/software/coreutils/target/debug$ ./od -j 11626525626624126226 a
od: tried to skip past end of input
1205315567243272026422
relunsec@relunsec:~/software/coreutils/target/debug$
when "a" content is "\nhello"
and then
relunsec@relunsec:~/software/coreutils/target/debug$ ./od -j 11626525626624126226 /usr/share/dict/words
od: tried to skip past end of input
1205315567243272026422
relunsec@relunsec:~/software/coreutils/target/debug$
as i see the input stay the same when i used -j with 11626525626624126226, it is a very weird behavior regardless of the file
even a is not the same as usr share dict words, it outputs the same number 1205315567243272026422
very interesting weird behavior

Research direction
Start by reproducing the uutils od command with -j 11626525626624126226 against the two inputs shown in the report. Trace the -j argument handling and compare the result with the expected rejection for an excessively large positive value; done means the invalid value is rejected consistently rather than producing the reported output.
