memory allocation of 4340410370284600376 bytes failed

Hello,

A typo lead to a bug discovery:

hexyl --terminal-width 2 1.txt
memory allocation of 4340410370284600376 bytes failed

It seems any terminal width less than 10 leads to a memory allocation issue.

Thank you for reporting this

How large is the 1.txt file?

This should work: wc -c 1.txt

I think this has to do with the (terminal_width - offset) calculation (taking a quick peek at main).

You can reproduce it with

▶ hexyl --terminal-width 2 <(echo "test")
memory allocation of 4340410370284600376 bytes failed

Looks very much just like an underflow in that subtraction, yes.
